Rivet Selection Guide: Types, Sizes, and How to Choose
Choosing the right rivet can make the difference between a secure, long-lasting assembly and one that fails under stress. Whether you’re building an aircraft, fabricating sheet metal enclosures, or repairing automotive bodywork, understanding rivet types and sizing principles ensures structural integrity and project success.
Rivets are permanent mechanical fasteners designed to join two or more materials by creating a clamped connection. Unlike threaded fasteners, they don’t require access to both sides of a joint—making them ideal for blind installations. They resist vibration better than bolts, distribute loads across a wider area, and can join dissimilar materials when properly selected.
This guide breaks down the six major rivet categories, explains how to calculate the correct diameter and length, and provides practical sizing formulas used by engineers worldwide. By the end, you’ll know exactly which rivet to specify for your next project.
Understanding the Six Major Rivet Categories
Rivets fall into distinct families, each engineered for specific applications and installation methods. Selecting the wrong type can compromise joint strength or complicate assembly.
1. Solid Rivets
Solid rivets are the oldest and most robust fastening solution available. A solid rivet consists of a shank and a head—typically rounded, conical, countersunk, flat, or oval. Installation requires inserting the rivet into a pre-drilled hole, then deforming the straight end using a hammer, rivet gun, or hydraulic press to create a second head that clamps the materials together.
During installation, the shank expands to fill the hole’s clearance, forming a tight, permanent joint. In critical applications—such as aircraft fuselages, bridges, and ship hulls—solid rivets are often heated to red heat to soften the metal, making deformation easier and producing a stronger bond.
Key applications: Aircraft assembly, bridge construction, shipbuilding, heavy steel structures
Advantages: Exceptional shear and tensile strength, vibration-resistant, proven reliability in high-stress environments
Limitations: Requires access to both sides of the joint, labor-intensive installation, specialized tooling for large-diameter rivets
2. Blind Rivets (Pop Rivets)
Blind rivets—commonly called pop rivets—revolutionized fastening by enabling installation from one side only. The assembly consists of a hollow shank and a mandrel (stem) running through the center. A rivet gun pulls the mandrel, causing the shank to expand and compress the materials. When sufficient clamping force is achieved, the mandrel snaps off with an audible “pop.”
Blind rivets are available in several configurations:
- Open-end rivets: Standard design with an exposed mandrel hole
- Closed-end rivets: Cup-shaped design that seals against moisture and air
- Multi-grip rivets: Wide grip range to accommodate varying material thicknesses
- Large-flange rivets: Wider bearing surface for soft or brittle materials
- Structural blind rivets: Heavy-duty versions approaching the strength of solid rivets
Key applications: Automotive bodywork, HVAC ductwork, electronics enclosures, appliance assembly, sheet metal fabrication
Advantages: One-sided installation, fast assembly, minimal tooling required, ideal for tubular or box sections
Limitations: Lower strength than solid rivets (except structural variants), mandrel hole may allow moisture ingress (unless closed-end)
3. Tubular Rivets
Tubular rivets resemble solid rivets but feature a partial hollow cavity extending into the shank from the tail end. This design reduces the force required for installation—only the thin walls around the cavity need to be flared outward to secure the joint.
Semi-tubular rivets have a shallow cavity (typically 112% of the shank diameter), while full-tubular rivets are hollowed deeper. Installation is performed with a press or setting tool that curls the hollow portion outward against the rear material.
Key applications: HVAC systems, light-duty brackets, leather goods, textiles, fiberboard assemblies
Advantages: Lower installation force than solid rivets, faster setting, suitable for softer materials
Limitations: Reduced strength compared to solid rivets, not recommended for high-stress applications
4. Split Rivets (Bifurcated Rivets)
Split rivets have a shank divided into two prongs that splay apart during installation. After inserting the rivet into a pre-drilled hole, the prongs are bent outward and flattened against the rear surface using a hammer or hand tool.
This design offers quick assembly without specialized equipment, making split rivets popular for low-volume production and field repairs.
Key applications: Leather goods, wood assemblies, plastics, thin metal panels, crafts, and upholstery
Advantages: No special tools required, fast installation, works well with soft materials
Limitations: Low tensile strength, unsuitable for structural loads, prone to loosening under vibration
Drive rivets are a simplified form of blind rivet with a short internal mandrel and a protruding pin on the rivet head. Installation involves placing the rivet in a pre-drilled hole and striking the pin with a hammer. The impact drives the mandrel into the shank, expanding it to grip the materials.
Drive rivets eliminate the need for a rivet gun, making them convenient for quick installations where modest strength is required.
Key applications: Signs, nameplates, thin sheet metal, light panels, point-of-sale displays
Advantages: Minimal tooling (just a hammer), fast installation, one-sided access
Limitations: Limited strength, not suitable for thick materials or high-stress environments
7. Structural Rivets
Structural rivets are heavy-duty blind rivets engineered to approach the performance of solid rivets. They feature thicker shanks, higher-strength materials, and often include a locking collar or grooved mandrel design to enhance joint integrity.
Some structural rivets retain the mandrel inside the shank after installation, providing additional strength and creating a watertight seal. These are commonly used in applications where vibration, dynamic loading, or environmental exposure is a concern.
Key applications: Automotive frames, truck trailers, steel construction, aerospace secondary structures, marine assemblies
Advantages: High shear and tensile strength, vibration-resistant, blind installation, tamper-proof
Limitations: Higher cost than standard blind rivets, requires more powerful installation tools
Rivet Head Styles and Their Applications
Head style affects bearing surface, clearance requirements, and aesthetic finish. Choosing the right head ensures optimal load distribution and compatibility with your assembly.
Dome (Button) Head: Rounded top with a wide bearing surface—general-purpose design used in most structural applications.
Countersunk Head: Sits flush with the material surface when installed in a countersunk hole. Essential for aerodynamic surfaces, sliding mechanisms, and tight-clearance assemblies.
Large-Flange Head: Extra-wide bearing surface prevents pull-through in soft materials (plastics, composites, fiberglass) or oversized holes.
Flat Head: Low-profile head with a flat top. Used where minimal protrusion is required but countersinking isn’t feasible.
Truss Head: Very low-profile, rounded shape. Provides a large bearing surface while maintaining minimal height above the workpiece.
Rivet Materials and Environmental Compatibility
Material selection depends on the base materials being joined, environmental exposure, and mechanical requirements. Mismatched materials can lead to galvanic corrosion—a critical failure mode where dissimilar metals create an electrochemical cell in the presence of moisture.
Aluminum: Lightweight with excellent corrosion resistance. The most common rivet material for general construction. Works well with aluminum sheets but can corrode when paired with steel in wet environments. Available in grades such as 5056 (high-strength) and 1100 (highly formable).
Steel: High tensile and shear strength. Carbon steel rivets are economical but require protective coatings (zinc plating, paint) to prevent rust—best for indoor, dry applications or when coated.
Stainless Steel: Superior corrosion resistance with excellent mechanical properties. Ideal for outdoor, marine, and chemical environments. Common grades include 304 (general-purpose) and 316 (marine-grade). Harder than aluminum, requiring pneumatic tools for blind rivet installation.
Copper: Excellent electrical and thermal conductivity. Naturally corrosion-resistant. Used in electrical assemblies, roofing, and decorative applications.
Brass: Copper-zinc alloy with good corrosion resistance and attractive finish. It cannot spark, making it suitable for explosive environments (oil and gas facilities). Often chosen for aesthetic appeal in architectural hardware.
Nylon and Plastic: Lightweight, non-conductive, and chemically resistant. Used in electronics, electrical panels, and environments where metal fasteners could cause shorts or corrosion.
Galvanic Corrosion Considerations
When dissimilar metals are joined, galvanic corrosion accelerates the deterioration of the less noble metal. To minimize risk:
- Match rivet material to the base material (aluminum rivets for aluminum sheets, stainless for stainless)
- Use stainless steel rivets as a universal option for most metals.
- Avoid pairing aluminum rivets with steel or copper in wet environments.
- Apply insulating washers or coatings when joining dissimilar metals.
How to Calculate Rivet Size: Diameter and Length
Proper sizing ensures adequate strength without over-engineering. Undersized rivets fail under load; oversized rivets weaken the base material by removing too much cross-sectional area.
Determining Minimum Shank Diameter
The minimum rivet diameter is based on the thickness of the thickest plate being joined. The standard formula is:
D_min = t_max × 3
Where:
- D_min = Minimum rivet shank diameter
- t_max = Thickness of the thickest plate
Example: If your thickest plate is 2.0 mm:
D_min = 2.0 mm × 3 = 6.0 mm
Consult a standard rivet size chart and select the next available size. In this case, suppliers typically offer 6.35 mm (1/4″) rivets.
Standard Rivet Diameters
Rivets are manufactured in standard increments. Here are the most common sizes:
Imperial (inches):
- 1/16″ (1.588 mm)
- 3/32″ (2.381 mm)
- 1/8″ (3.175 mm)
- 5/32″ (3.969 mm)
- 3/16″ (4.763 mm)
- 1/4″ (6.350 mm)
- 5/16″ (7.938 mm)
- 3/8″ (9.525 mm)
Metric (millimeters):
- 2.0 mm
- 2.4 mm
- 3.0 mm
- 3.2 mm
- 4.0 mm
- 4.8 mm
- 5.0 mm
- 6.0 mm
Calculating Rivet Length
Rivet length must account for the total thickness of all materials being clamped (grip range) plus an allowance for forming the closing head. The formula is:
L = S + A
Where:
- L = Required rivet shank length
- S = Total thickness of all materials (grip range)
- A = Allowance for forming the closing head
The allowance A is calculated as:
A = D × c
Where:
- D = Rivet diameter
- c = Multiplier constant based on head type and application
Multiplier constants (c):
Typical Multiplier Constants (c) for Common Rivet Head Types:
– Dome (button) head: c = 1.5
– Countersunk head: c = 1.2
– Flat head: c = 1.3
– Large-flange head: c = 1.6
– Truss head: c = 1.4
These values are standard starting points; always consult manufacturer data for precise values in critical applications. Example calculation:
You need to join:
- 5.0 mm acrylic sheet
- 2.0 mm aluminum angle bar
Step 1: Calculate minimum diameter
- t_max = 5.0 mm
- D_min = 5.0 × 3 = 15.0 mm
- Choose standard size: 15.875 mm (5/8″) or 16 mm (if available)
Step 2: Calculate total grip range
- S = 5.0 mm + 2.0 mm = 7.0 mm
Step 3: Calculate allowance (general construction, dome head, D ≤ 20 mm)
- c = 1.5
- A = 15.875 × 1.5 = 23.8 mm
Step 4: Calculate the required length
- L = 7.0 + 23.8 = 30.8 mm
- Choose standard length: 32 mm (closest available)
Understanding Grip Range
Many blind rivet manufacturers specify a grip range rather than an exact length. Grip range indicates the minimum and maximum thicknesses of material a rivet can securely fasten.
For a 3.2 × 12.7 mm (1/8″ × 1/2″) rivet:
- Diameter: 3.175 mm
- Length: 12.7 mm
- Grip range ≈ L – 1.5D = 12.7 – (1.5 × 3.175) ≈ 7.9 mm
This rivet can clamp materials with a combined thickness between approximately 5 mm and 7.9 mm.
Selecting the Correct Drill Bit Size
Rivet holes must be precisely sized. Too tight, and the rivet won’t insert; too loose, and the joint won’t achieve full clamping force.
General rule: Drill holes 0.001″ to 0.006″ (0.025 mm to 0.15 mm) larger than the rivet diameter.
Recommended Hole Diameters
Sample Recommended Hole Diameters for Common Rivet Sizes:
To help you choose the correct drill bit, here are typical hole diameters for a few common rivet sizes:
– 1/8 inch (3.2 mm) rivet: Drill a 3.3 mm or #30 drill bit hole
– 3/16 inch (4.8 mm) rivet: Drill a 5.0 mm or #11 drill bit hole
– 1/4 inch (6.4 mm) rivet: Drill a 6.5 mm or F drill bit hole
– 5/32 inch (4.0 mm) rivet: Drill a 4.1 mm or #20 drill bit hole
– 3/32 inch (2.4 mm) rivet: Drill a 2.5 mm or #41 drill bit hole
These recommendations offer a slight clearance while providing a secure fit. Always check the manufacturer’s specifications for precise requirements in critical applications. For most applications, use a drill bit matching the rivet nominal size. The slight clearance from the drill bit’s tolerance is usually sufficient.

Step 7: Verify hole size
- Drill holes 0.001″–0.006″ larger than rivet diameter
- Use the standard drill bit closest to the rivet nominal size.
Rivet Strengths: Shear and Tensile Performance
Two strength values characterize rivet performance:
Shear strength: The force required to cause the rivet to fail when materials slide in opposite directions perpendicular to the rivet axis. This is the most common loading condition.
Tensile strength: The force required to pull joined materials apart along the rivet’s axis.
Strength depends on:
- Rivet type (solid rivets are strongest)
- Material (steel > stainless steel > aluminum)
- Diameter (larger rivets carry more load)
- Installation quality (proper deformation critical)
Always consult manufacturer datasheets for specific strength ratings. For critical applications, calculate the total load and apply a safety factor (typically 2 to 4 times) when determining rivet quantity and size.
Sample Calculation: Determining Rivet Quantity for a Structural Joint
Suppose you need to join two steel plates that will experience a maximum shear load of 10,000 N. The rivets you have selected have a rated shear strength of 2,500 N each (check manufacturer datasheets). To ensure safety, apply a safety factor of 3.
1. Calculate the design load:
Design Load = Maximum Load x Safety Factor = 10,000 N x 3 = 30,000 N
2. Determine the minimum number of rivets required:
Minimum Quantity = Design Load / Shear Strength per Rivet = 30,000 N / 2,500 N = 12 rivets
3. Round up to the next whole number to ensure adequate strength.
Result: Use at least 12 rivets of the specified size and rating, spaced appropriately according to engineering standards, to carry the expected load in this application safely.
By working through these calculations, you can translate theoretical strength ratings into practical rivet selection for any project. Always review engineering codes or consult with a professional for critical or safety-sensitive structures.
Common Rivet Selection Mistakes to Avoid
Using aluminum rivets with steel in outdoor applications: Galvanic corrosion will rapidly degrade the aluminum. Use stainless steel rivets instead.
Undersizing rivet diameter: Leads to premature failure under load. Always follow the 3× thickness rule for minimum diameter.
Oversizing holes: Excessive clearance prevents proper clamping. Stay within 0.006″ maximum clearance.
Choosing blind rivets for structural loads: Standard blind rivets have lower strength than solid rivets. Use structural blind rivets or solid rivets for high-stress applications.
Ignoring grip range: Installing a rivet outside its grip range results in weak joints. Verify total material thickness falls within the rivet’s specified grip range.
Poor hole preparation: Burrs, misalignment, and rough edges compromise joint strength. Deburr all holes and ensure proper alignment before installation.
Why Rivet Selection Matters for Project Success
Selecting the correct rivet type and size directly impacts structural integrity, durability, and safety. Undersized or improperly installed rivets can fail catastrophically, leading to costly repairs, product recalls, or—in critical applications like aircraft—loss of life.
Proper rivet selection ensures:
- Load distribution: Correctly sized rivets spread forces across the joint, preventing stress concentrations
- Vibration resistance: Rivets maintain clamping force better than threaded fasteners in dynamic environments
- Environmental durability: Material compatibility prevents galvanic corrosion and premature failure
- Assembly efficiency: Right-sized rivets install cleanly without excessive force or rework
Whether you’re a DIY enthusiast working on a home project or a professional engineer designing safety-critical structures, understanding rivet types and sizing formulas empowers you to make informed decisions. Taking time to calculate diameter, verify grip range, and match materials to environmental conditions pays dividends in long-term reliability.
The next time you reach for a rivet gun, you’ll know exactly which rivet to use—and why it will hold. With this knowledge, you can confidently tackle any project, big or small.
How to Remove Rivets
Removing rivets may seem challenging at first, but with the right tools and techniques, it can be done efficiently and safely. The most common method involves drilling out the rivet head. Follow these steps:
- Select the Right Drill Bit: Choose a drill bit that matches the size of the rivet head. Typically, this is slightly smaller than the rivet shaft’s diameter.
- Prepare the Workspace: Ensure the area around the rivet is stable and clear of any obstacles. Wear safety goggles to protect against flying debris.
- Align the Drill: Position the drill bit at the center of the rivet head. Keep the drill steady to avoid slipping or damaging the surrounding material.
- Drill Through the Head: Start drilling carefully, applying light pressure. The goal is to remove just the rivet head. Once the head detaches, the rivet’s shaft will often fall out or can be gently pushed through.
- File or Smooth the Area: After the rivet is removed, smooth any rough edges left behind using a file or sandpaper to prepare the surface for replacement if needed.
For stubborn or specialty rivets, additional tools, such as rivet-removal tools or grinding equipment, may be required. Always follow proper safety precautions when removing rivets to ensure both accuracy and personal safety. Be aware of potential risks, including sharp edges, hot metal from grinding or drilling, and the dangers of working in confined spaces where ventilation or access may be limited. Always let metal cool before handling, remove sharp debris promptly, and ensure the work area is well-lit and well ventilated. Taking these steps helps you prepare for real-world hazards and avoid injuries during rivet removal.
Rivet Removal Tools You Might Need
- Drill with a Metal Drill Bit
A standard drill with appropriately sized metal drill bits is one of the most common tools used for rivet removal. Select a drill bit slightly larger than the rivet’s mandrel but smaller than the rivet’s flange for best results. - Rivet Removal Tool
Purpose-built rivet removal tools are designed for simplicity and precision. These tools often include a guide that centers over the rivet, ensuring clean and accurate removal with minimal damage to surrounding materials. - Angle Grinder
For heavy-duty or oversized rivets, an angle grinder can be used to grind off the rivet head. This tool is excellent for situations where conventional drilling is not practical. - Center Punch
A center punch is handy for marking the center of the rivet head before drilling. This step prevents the drill bit from slipping and ensures a clean hole in the center. - Chisel and Hammer
For soft materials or smaller applications, a chisel and hammer can be used to break the rivet head off manually. This method is more labor-intensive and requires precise control. - Rotary Tool (e.g., Dremel)
A rotary tool fitted with a cutting attachment is ideal for removing rivets in tight spaces or delicate projects, providing precision in challenging areas. - File or Sandpaper
After rivet removal, a file or sandpaper can help smooth the surface, addressing any sharp edges left behind and preparing the material for a new rivet or repair.
These tools offer a range of options for virtually any rivet-removal job, and choosing the right tool depends on the rivet’s size, material, and placement. Always wear safety equipment such as gloves and goggles to protect against potential hazards.
How to Use a Rivet Removal Tool
Using a rivet removal tool correctly ensures safety and effectiveness. Follow these steps to remove rivets from a surface properly:
- Assess the Rivet and Surface
Identify the type of rivet and the material it is attached to. This helps you choose the appropriate rivet removal tool and method for the task. - Mark the Center of the rivet.
Using a center punch, mark the exact center of the rivet head. This prevents the drill bit or removal tool from sliding off during the process. - Prepare the Rivet Removal Tool
Set up the rivet removal tool according to the manufacturer’s instructions. For drill-based tools, ensure the proper drill bit size matches the rivet shaft. - Drill or Cut the Rivet
Place the drill or removal tool on the center mark and apply steady pressure. Work carefully to drill through the rivet head without damaging the surrounding material. - Detach the Rivet Head
Once the rivet head is loosened or separated, use pliers or a flathead screwdriver to remove it completely. - Push Out the Rivet Shaft
After the head is removed, gently push the rivet shaft out of the hole using a punch tool or similar implement. - Clean and Inspect the Surface
After removal, use a file or sandpaper to smooth any rough edges left behind. Inspect the material to ensure it’s ready for repairs or a new rivet.
Following these steps will help you remove rivets efficiently while minimizing potential damage to the material. Always prioritize safety by wearing appropriate protective gear.
Health and Safety: Hands & Eye Protection
