Self-Clinching Nuts(S/CLS)

When pressed into ductile material, a self clinching fastener (commonly referred to as a clinch nut or press nut) displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank or pilot of the fastener.
A serrated clinching ring, knurl, ribs, or hex head prevents fastener rotation in the host material once inserted – becoming a permanent part of the piece into which it's installed.
