SELF-CLINCHING NUTS

SELF-CLINCHING NUTS 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. Types S/SS/CLS/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”/0.8mm...
