How to Use a Pop Rivet Gun: A Step-by-Step Guide

Using a pop rivet gun can be an intimidating task, especially if you’re new to this type of tool. But with the right techniques and precautions, you’ll be able to master it quickly. In this article, we’ll guide you through the process of using a pop rivet gun safely and effectively.

What is a Pop Rivet Gun?

A pop rivet gun, also known as a spin riveter or pneumatic riveter, is a tool used to set and form a blind rivet, a type of fastener with no exposed tail. This versatile tool is commonly used in various industries, such as construction, automotive, aviation, and manufacturing. There are two main types of pop rivet guns: manual and pneumatic. Manual guns require muscle power to set the rivets, while pneumatic guns use compressed air.

Preparation

Before you start using a pop rivet gun, ensure that you:

  • Follow all safety guidelines and recommendations in the user manual or provided by the manufacturer
  • Wear appropriate personal protective equipment (PPE) including safety glasses, earplugs, and a dust mask (if working in a dusty environment)
  • Choose the right-sized blind rivets for the thickness and type of materials being joined
  • Place a rivet set (provided by the manufacturer) at the end of the barrel for proper rivet loading and alignment
  • Charge your pneumatic gun according to the manufacturer’s instructions
  • Position yourself to easily access the workpiece with the rivet gun handle

Step-by-Step Procedure

The step-by-step procedure for using a pop rivet gun is as follows:

StepDescriptionIllustrated Example
1Insert the rivet into the rivet set, aligning it with the handle and ensuring it is secure.
2Prime the gun by setting the air pressure according to the manufacturer’s instructions, which may include a release handle or valve.
3Load the gun, placing the rivet-nose over the blind hole in the workpiece and ensuring the rivet tail is properly seated in the rivet set.
4Squeeze the rivation handle, which usually located on the side or end of the gun. Hold the handle firmly while pushing the rivet out the other side of the material.
5Allow the rivet to expand (or "pop"), forming the rivet shank and connecting the two materials. Repeat as needed.
6Monitor the riveting pattern, adjusting the setting for proper coverage and visibility when necessary.
7Periodically check the tool to ensure proper cleaning, lubrication, and performance.

Important Considerations

When using a pop rivet gun:

  • Keep children away from the workspace during operation to avoid injuries from flying debris or loud sounds.
  • Stay behind the workpiece, when possible, to ensure adequate clearance from the tools’ path and prevent unintended objects from interfering with the work.
  • Cleanliness is crucial: Prevent the buildup of contaminants in the barrel by regularly cleaning the interior surfaces with compressed air and maintaining a consistent lubricating flow.
  • Control ambient temperature and prevent use in extremely cold, windy, or humid environments. This will help improve handling and ensure proper setability.
  • Set reasonable expectations regarding the capacity, speed, and endurance of your equipment. Incomplete or loose rivet setups can compromise the join integrity.

Troubleshooting Common Issues

  1. Stuck Rivet: Clean the surrounding area and check for hidden screws or other obstructions; use compressed air and carefully re-seat the rivet.
  2. Faulty Rivet Shank Formation: Ensure proper grip force, cleaning, and the suitability of the rivets with the workpiece and loading conditions.
  3. Rivet Gun Difficulty Spinning: Check pressure level, maintain proper setting techniques, and ensure rivets are aligned correctly on both sides.

Conquering Your First Blind Rivet Join

Getting a feel for the grip pressure, trigger control, and proper handling of your new pop rivet gun is crucial. Practice first to develop your skills on low-stress materials to better understand the process:

MaterialThickness
Aluminum10mm (3/8"), 5mm (0.2") and higher
Steel10mm (3/8"), 5mm (0.2") and higher
ABS plastics5mm (0.2"), and higher
Higher thickness and more sensitive operations may require specialized advice.

Remember to set appropriate air pressure, secure and align the rivets with the handle, monitor coverage, and adjust grip accordingly. Don’t stress or rush, as inaccuracy can result in the material being over-processed.
