A rivet having a cylindrical head portion, a cylindrical shoulder portion of reduced diameter and a tenon portion of further reduced diameter is projected through first and second parts which are to be fastened together. The head portion abuts one side of the first part, the shoulder portion extends a substantial distance through an opening in the first part and the tenon portion projects through and beyond a hole in the second part. An axial bore opens through the head portion and extends into the shoulder portion but stops short of the tenon portion, the bore terminating in an end wall. A first tool is projected into the bore and bears against the end wall to place substantially all of the shoulder portion in tension and to hold the rivet while a second tool engages the tenon portion to deform the latter and form an enlargement engaging the second part, the tenon portion thereby being in compression. The force of tension is greater than the force of compression so that the residual force in the rivet after the latter has been released by the tools is a tensile force.

Rivet and method of using the same

A transmission selector is mounted on the floor of an automobile by elastomeric S-shaped straps which permit the selector to move back and forth in a longitudinal direction while holding the selector substantially rigid in vertical and transverse directions.
