Self-Clinching Nuts - Types SP, SMPP - Unified
Nuts (all) for Installing into Stainless Steel – Type SP, SMPP
Self-clinching nuts are installed by placing them in properly sized holes in sheets and applying a parallel
squeezing force to the head of the nut. The sheet metal surrounding the head cold flows into an undercut thereby
making the fastener an integral part of the sheet. A serrated clinching ring prevents the fastener from rotating after
installation.
Type S, SS, CLS, and CLSS nuts provide load-bearing threads in thin sheets with high pushout and torque-out resistance.
Type SP, PEM 300® nuts provide strong load-bearing threads in stainless steel sheets as thin as .030”.
