Understanding Rivets and Rivet Guns: Your Fastening Fundamentals
Before you dive into a project, it’s crucial to understand what rivets are and how rivet guns work. Rivets create a permanent mechanical fastener, ideal for situations where you need strength without the heat of welding or the potential loosening of screws.
A rivet consists of two main parts: the head and the mandrel (or stem). The rivet gun pulls the mandrel, deforming the rivet’s body to create a “blind” head on the backside of your material. This forms a tight, secure joint.
Types of Rivets
Different projects call for different rivets. Choosing the right one is key to a strong connection.
- Blind Rivets (Pop Rivets): These are the most common for DIYers. You can install them from one side of the material, hence “blind.” They come in various materials.
- Solid Rivets: These require access to both sides of the material for installation, typically hammered or pressed. They offer superior strength but are less common for casual DIY.
- Rivet Materials: Rivets are made from aluminum, steel, stainless steel, or copper. Match the rivet material to your workpiece to prevent galvanic corrosion, especially outdoors.
Types of Rivet Guns
The tool you use to set rivets also varies. Each type has its advantages.
- Manual Hand Riveters: These are the most affordable and common for occasional use. They require physical effort to squeeze the handles.
- Lever Riveters: Similar to hand riveters but with longer handles for increased leverage, making them easier to use for larger rivets or repetitive tasks.
- Pneumatic (Air) Riveters: Powered by an air compressor, these are fast and effortless, perfect for high-volume work.
- Cordless Battery Riveters: Offering portability and power, these are a great option for professional use or serious DIYers who need to work away from air lines.
Essential Tools and Materials Before You Start Riveting
Having the right gear on hand makes all the difference. Don’t start a project only to realize you’re missing a crucial piece.
Here’s what you’ll need:
- Rivet Gun: Choose one appropriate for the rivet sizes you plan to use. Most manual guns come with interchangeable nosepieces.
- Rivet Assortment: Have various diameters and lengths on hand. Ensure they match your material and project needs.
- Electric Drill or Cordless Drill: For creating pilot holes.
- Drill Bit Set: You’ll need bits precisely sized for your rivets. A good rule of thumb is to use a drill bit 0.002 to 0.004 inches larger than the rivet’s diameter.
- Center Punch: To mark your drilling spots accurately and prevent the drill bit from wandering.
- Deburring Tool or File: To clean up the edges of your drilled holes.
- Clamps: To hold your workpieces together securely during drilling and riveting.
- Measuring Tape and Marker: For accurate placement.
- Safety Glasses and Gloves: Non-negotiable for any workshop task.
Safety First: Protecting Yourself While Riveting Metal
Working with metal and power tools always requires a strong emphasis on safety. Don’t skip these steps.
- Eye Protection is Paramount: Small metal shavings and the snapping mandrel can become projectiles. Always wear ANSI-approved safety glasses.
- Hand Protection: Gloves protect your hands from sharp metal edges and provide a better grip on your tools.
- Secure Your Workpiece: Use clamps to hold the metal firmly. A shifting workpiece is a recipe for injury or an inaccurate rivet.
- Proper Ventilation: While riveting itself doesn’t produce fumes, drilling and deburring can create fine metal dust. Work in a well-ventilated area.
- Mind Your Fingers: Keep your fingers clear of the rivet gun’s moving parts, especially when squeezing the handles.
- Clean Workspace: A tidy area reduces tripping hazards and helps you find your tools easily.
Step-by-Step Guide: How to Use a Rivet Gun on Metal Effectively
Now, let’s get down to the practical steps of setting a rivet. Follow these instructions carefully for strong, reliable joints.
1. Mark and Punch Your Rivet Locations
Accurate placement is critical. Use a marker to pinpoint where each rivet will go.
Then, use a center punch and hammer to create a small indentation at each mark. This prevents your drill bit from “walking” across the metal surface.
2. Drill the Pilot Hole
Select a drill bit that is slightly larger than the rivet’s diameter. For example, if you have a 1/8-inch rivet, use a 9/64-inch drill bit.
Drill straight through both pieces of metal you intend to join. Apply steady pressure and let the drill do the work.
3. Deburr the Holes
After drilling, metal edges will have burrs – sharp, raised edges. These can prevent the pieces from sitting flush and weaken the joint.
Use a deburring tool or a small file to smooth out the edges of each hole on both sides. This ensures a clean, tight fit for the rivet.
4. Select the Right Rivet and Nosepiece
Choose a rivet with the correct diameter and grip range for your material thickness. The grip range is the total thickness of the materials being joined.
Match the rivet gun’s nosepiece to the diameter of your chosen rivet. Most rivet guns come with several interchangeable nosepieces.
5. Load the Rivet Gun
Insert the rivet’s mandrel (the long pin) into the correct nosepiece of the rivet gun until the rivet head rests against the gun. It should fit snugly.
Ensure the rivet is seated fully and straight.
6. Insert and Set the Rivet
Align the rivet’s shaft with the drilled hole in your metal pieces. Push the rivet through both pieces until the rivet head is flush against the top surface.
Squeeze the rivet gun handles firmly and consistently. You’ll feel resistance as the gun pulls the mandrel, causing the rivet to expand and create a blind head on the backside.
Continue squeezing until you hear a distinct “pop” sound. This indicates the mandrel has snapped off, and the rivet is fully set.
7. Check the Connection
After the pop, release the rivet gun handles. The spent mandrel will fall out or be ejected.
Inspect the rivet. It should be tight, flush with the surface, and hold the two pieces of metal together without any wobble.
Common Riveting Challenges and How to Overcome Them
Even experienced DIYers encounter issues. Knowing how to troubleshoot will save you time and frustration when you use a rivet gun on metal.
- Rivet Not Setting/Mandrel Not Breaking: This often means the rivet gun isn’t applying enough force, or the rivet is too large for the gun. Try a lever-type or pneumatic gun for larger rivets. Ensure you’re squeezing the handles completely.
- Wobbly Rivets: A wobbly rivet usually indicates the hole was drilled too large for the rivet, or the grip range was incorrect. Ensure your drill bit matches the rivet diameter properly and the rivet length accommodates your material thickness.
- Material Distortion: Applying too much force with a pneumatic gun or using a rivet that’s too long can buckle thin metal. Use appropriate rivet sizes and adjust pressure if possible. Clamping your work tightly helps prevent this.
- Rivet Head Not Flush: Burrs around the hole or debris can prevent the rivet head from sitting flat. Always deburr your holes thoroughly.

Maintaining Your Rivet Gun for Lasting Performance
A little care goes a long way in ensuring your rivet gun performs reliably for years.
- Clean After Each Use: Remove any spent mandrels or metal shavings from the nosepiece and jaw assembly. A small brush or compressed air works well.
- Lubricate Moving Parts: Apply a light machine oil to the pivot points and jaw mechanism of manual rivet guns. For pneumatic guns, follow the manufacturer’s lubrication instructions for the air motor.
- Inspect Nosepieces: Check the various nosepieces for wear or damage. Replace them if they are deformed, as this can lead to improper rivet setting.
- Store Properly: Keep your rivet gun in a dry place, preferably in its original case or a dedicated toolbox, to protect it from dust and damage.
Frequently Asked Questions About Riveting Metal
What size drill bit do I use for a rivet?
Use a drill bit that is slightly larger than the rivet’s diameter. For example, for a 1/8-inch rivet, use a 9/64-inch drill bit. This slight clearance allows the rivet to pass through easily but still ensures a tight fit when set.
Can you remove rivets once they are installed?
Yes, you can remove rivets. The most common method is to drill out the head of the rivet using a drill bit slightly larger than the rivet’s mandrel, but smaller than the rivet head. Once the head is drilled through, the rest of the rivet can be punched out.
What is the difference between a rivet and a screw?
A rivet creates a permanent mechanical bond by deforming its body to hold materials together, installed from one side (blind rivet) or two (solid rivet). A screw creates a temporary, threaded connection that can be easily removed and reinstalled. Rivets are generally stronger and more resistant to vibration for permanent applications.
How do I know what length rivet to use?
To determine the correct rivet length, measure the total thickness of the materials you are joining (the grip range). The rivet’s specified grip range should match or slightly exceed this measurement. Always check the rivet manufacturer’s specifications for exact grip range recommendations.
Learning how to use a rivet gun on metal is a fantastic addition to any DIYer’s skillset. It empowers you to create strong, lasting repairs and fabrications with confidence. Remember to prioritize safety, choose the right tools and materials, and practice these steps.
With a little patience, you’ll be setting professional-grade rivets in no time. So grab your rivet gun, find your next project, and get ready to make some solid connections!
