4.0 x 8 Steel Blind Rivets (Sold Individually)

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. Unlike solid rivets, blind rivets can be installed in joints from only one side of the part—making them “blind” to the opposite side.
