Rivet Guns

A rivet gun is a tool used to install blind rivets in FRC. It works by pulling a mandrel through the rivet body, expanding it and locking materials together permanently.

Types of Rivet Guns

Hand Rivet Gun

Manually operated with handles

Most common in FRC teams

Good for small to medium build volume

Pneumatic Rivet Gun

Much faster and requires less effort

Used in high-volume assembly during build season

How a Rivet Gun Works

Insert rivet into the drilled hole

Place rivet gun nose onto the mandrel

Squeeze or activate the tool

The mandrel is pulled, expanding the rivet

The mandrel snaps off once fully set

Proper Use

Ensure correct rivet size and grip range before installing

Keep the gun aligned straight with the rivet

Apply steady force until the mandrel breaks cleanly

Make sure the rivet head sits flush against the material

Common Mistakes

Pulling at an angle (can weaken the joint)

Not fully setting the rivet

Using the wrong nose piece for the rivet size

Reusing partially set rivets

Maintenance

Empty broken mandrels from the tool regularly

Keep jaws clean for proper gripping

Check nose pieces for wear or damage

Key Idea

Rivet guns turn a simple blind rivet into a strong, permanent joint. Proper alignment, correct sizing, and full actuation are essential for reliable FRC construction.
