3\16*0.55 Pop Rivets

is a type of fastener used to join two or more materials together, especially when access to the back of the materials is limited or impossible. Pop rivets consist of two main parts: the rivet body and the mandrel.

Here’s how a pop rivet works:

1. Rivet Body: The rivet body is a hollow cylindrical shaft with a flanged head at one end. The other end of the rivet body is open.
2. Mandrel: The mandrel is a thin rod or stem that fits inside the hollow rivet body. One end of the mandrel is usually shaped to fit into a tool called a rivet gun.
