FAQ
Solid rivet vs pop rivet?
A solid rivet is stronger and needs access to both sides plus a bucking process. A pop rivet installs blind from one side with a simple tool, at lower strength.
How do you set a solid rivet by hand?
Insert through the hole, back the parts against a bucking bar on the manufactured-head side, and hammer or squeeze the tail into a rounded shop head.
