How to Use a Pop Rivet Gun: A Step-by-Step Guide
Pop rivets are a popular way to fasten materials like metal, plastic, and more. The pop rivet gun, often simply called a “riveter,” is an essential tool for both professionals and DIY enthusiasts. If you’ve ever wondered how to use a pop rivet gun, this in-depth guide will walk you through the process, highlight key tips, and address common challenges.
Understanding Pop Rivet Guns
Pop rivet guns are hand-held or pneumatic tools designed to secure “blind rivets” (pop rivets) in place. These rivets are unique because they can be installed from one side of the workpiece, making them perfect for many assembly and repair tasks. Popular both in workshops and on job sites, they are found in industries ranging from automotive to home improvement.
Key Types of Pop Rivet Guns
- Manual Rivet Guns: Operated by hand, ideal for light to medium tasks.
- Pneumatic/Air Rivet Guns: Powered by compressed air, suitable for heavy-duty or industrial jobs.
- Battery/Electric Rivet Guns: Cordless and portable, great for mobility and larger projects.
How Does a Pop Rivet Gun Work?
At the heart of the pop rivet process are the rivet itself and the gun. The gun pulls a pin (mandrel) through the rivet, expanding it and locking the material together. Once tightened, the pin snaps off, leaving a neat, sturdy connection.
Step-by-Step Guide: How to Use a Pop Rivet Gun
Follow these straightforward steps for a successful rivet installation:
1. Gather Your Materials
Before you start, make sure you have:
- The appropriate pop rivet gun (manual, pneumatic, or battery)
- Pop rivets of the correct size and material
- The materials to be fastened (e.g., two sheets of metal or plastic)
- A drill and the correct drill bits
- Safety glasses and gloves
2. Prepare the Work Pieces
- Align the materials you want to join so that their surfaces are flush.
- Mark the points where you want the rivets to go.
- Clamp the materials if necessary to prevent shifting.
3. Drill Holes
- Select a drill bit that matches the diameter of your pop rivet.
- Drill a hole through both pieces of material at each marked point.
- Remove any burrs or debris to ensure a clean fit.
4. Load the Pop Rivet Gun
- Insert the mandrel (the long pin on the rivet) into the nosepiece of the gun.
- Push until the rivet head touches the nose of the gun.
5. Insert the Rivet Into the Material
- Slide the body of the rivet through the drilled holes until the head is flush with the surface.
6. Operate the Rivet Gun
- Manual Gun: Squeeze the handles firmly. You may need to pump the handles several times.
- Pneumatic/Battery Gun: Activate the trigger to pull the mandrel.
- You’ll hear a “pop” when the mandrel snaps, indicating the rivet is secure.
7. Remove the Mandrel
- The broken mandrel will remain in the gun. Release or discard it according to your tool’s instructions.
8. Inspect the Rivet
- Check for tightness and ensure the rivet is flush with the material surface.
Benefits of Using Pop Rivet Guns
Pop rivet guns offer several advantages for fastening tasks:
- Blind Installations: Only one side of the workpiece needs to be accessible.
- Speed: Quick and efficient connections.
- Strength: Reliable joins for a variety of materials.
- Versatility: Usable on metal, plastic, leather, and more.
- Clean Finish: Leaves a neat appearance with minimal disturbance.
Common Challenges and How to Overcome Them
Even with their user-friendliness, pop rivet guns come with some potential obstacles:
- Wrong Hole Size: Too small or too large holes can weaken the connection. Always drill to the correct size for your rivet.
- Stuck Mandrels: Sometimes the snapped mandrel gets stuck in the tool. Clean your gun regularly and follow manufacturer guidelines.
- Material Cracking: Over-tightening can cause brittle materials to crack. Stop when you hear the rivet “pop” and don’t force extra pressure.
- Misaligned Pieces: Use clamps and double-check before drilling to ensure a perfect fit.
- Worn Nosepieces: Nosepieces wear over time. Replace them as needed for cleaner rivets.
Practical Tips and Best Practices
To get the most out of your pop rivet gun:
- Match Material Types: Use aluminum rivets for soft materials and steel or stainless-steel rivets for tougher jobs.
- Lubricate Your Gun: Especially with pneumatic models, regular lubrication keeps moving parts in good shape.
- Test on Scraps: Before working on your final piece, practice rivet placement on spare material to perfect your technique.
- Organize Rivet Sizes: Keep a range of rivet sizes on hand and clearly labeled for each application.
- Wear Safety Gear: Always use safety glasses and gloves to protect against flying debris and sharp metal edges.
- Check Rivet Length: Rivets should be long enough to grip both materials securely, but not so long that the joint is weak or unsightly.
- Regular Maintenance: After each use, remove any remaining mandrel pieces and clean the gun. For air-powered models, check airline fittings and pressure.
Cost Tips: Saving on Rivet Guns and Shipping
When it comes to buying pop rivet guns and related supplies, a few strategies can help you save:
- Bundle Purchases: Many suppliers offer sets with a variety of nosepieces and rivet starter packs—these can be more cost-effective than buying separately.
- Compare Models: Entry-level hand rivet guns cost less, but higher-end pneumatic or electric versions pay off for frequent users with time and labor savings.
- Factor in Shipping: Some online retailers offer free or discounted shipping, especially for bulk orders. Look for “Free Shipping” promotions or minimum order amounts.
- Buy Local (When Possible): Hardware stores may offer competitive prices without shipping costs or delivery waits.
- Warranty Considerations: Spending a little more for robust warranty coverage or reputable brands can reduce long-term replacement costs.

Troubleshooting Common Pop Rivet Gun Issues
If you run into problems with your pop rivet gun, try these troubleshooting tips:
- Rivet Won’t Pop: Check if the mandrel is seated correctly and the hole is clear. Try a lighter squeeze or adjust the air pressure on pneumatic models.
- Mandrel Jams in Nosepiece: Use needle-nose pliers to remove the stuck piece, or disassemble the nosepiece as per the manufacturer’s instructions.
- Inconsistent Rivet Tightness: Make sure you are using the correct-sized rivet and apply steady, even pressure.
- Tool Fatigue: For repetitive tasks, upgrade to a pneumatic or battery-powered tool to reduce strain.
- Leaking Air (on Pneumatic Models): Replace worn seals and check that the hose fittings are secure.
