FAQ
How does a pop rivet work?
The tool pulls the mandrel through the body. The mandrel head expands the body behind the workpiece, then the mandrel snaps at its break point, leaving a flush, permanent clamp.
What size pop rivet should I use?
The grip range must span the total material thickness. Choose a body diameter about 1/8 in. smaller than the hole, and match body material to the workpiece to avoid corrosion.
