Unlock the Secrets of Flawless Riveting

Unleash your inner DIY superhero and conquer the world of riveting with self-piercing gun riveters. These powerful tools can transform your metalworking projects into masterpieces, but like any tool, they’re not immune to occasional hiccups. Fear not, brave riveter! This comprehensive guide will empower you to diagnose and resolve common issues with self-piercing gun riveters, ensuring seamless riveting adventures.

1. Rivets Not Setting Properly

The culprit could be a faulty rivet mandrel. Replace it with a fresh one to see if the problem persists. If not, check the rivet size compatibility with the riveter and adjust accordingly. Insufficient force or improper alignment can also hinder riveting. Ensure the rivet is perpendicular to the materials and apply steady pressure until you hear a distinct “pop.”

2. Riveter Leaking Air

If you hear a hissing sound, it indicates an air leak. Inspect the air lines and fittings for any damage or loose connections. Tighten or replace as needed. Additionally, check the air filter and replace it if necessary.

3. Riveter Not Tripping

A jammed trigger or a dirty plunger can prevent the riveter from tripping. Disassemble the tool and clean the trigger mechanism with a soft brush. Lubricate the plunger to ensure smooth operation.

4. Rivet Heads Not Breaking

Ensure you’re using the correct rivet puller. The wrong size or a worn-out puller can lead to incomplete head splitting. Replace the puller if needed. Check the jaw alignment as well; it should be parallel to the rivet heads.

5. Riveter Not Pulling Mandrel

A jammed collet or a broken mandrel release lever can hinder mandrel extraction. Disassemble the riveter and clear any debris from the collet and release lever. If the lever is damaged, replace it promptly.


Armed with this troubleshooting arsenal, you’ll be an unstoppable riveting force. Remember, practice makes perfect. The more you wield your self-piercing gun riveter, the more familiar you’ll become with its quirks and the easier it will be to overcome any obstacles. So, don’t let minor setbacks hold you back. Embrace the challenge, and let the rivets sing their symphony of secure connections!
