Rivet, blind, half stainless steel, 3.2 x 10 mm, Fastbolt.

Blind rivets, a.k.a. break stem rivets, are tubular fasteners with a mandrel through the center. Blind rivets are inserted into drilled holes in the parts to be joined, and a special tool is used to draw the mandrel through the body of the rivet. The blind end expands, and the mandrel is snapped off. Stainless steel is a family of iron-based alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting, as well as providing heat-resistant properties.
