Crown Bolt 3/16 in. x 3/8 in. Stainless Steel Rivet and Stainless Steel Mandrel Grip Range (4-Pack)

Blind rivets are tubular and are supplied with a mandrel through the center. The rivet assembly is inserted into a hole drilled through the parts to be joined and a specially designed tool is used to draw the mandrel into the rivet. This expands the blind end of the rivet and then the mandrel snaps off. Each rivet has a minimum and maximum grip range that allows for selection of the proper size based on combined thickness of the materials being joined together.
