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. Type SMPS nuts are for thinner sheet/ close-to-edge applications - PAGE 7 Types S/SS/CLA/CLS/CLSS nuts provide load-bearing threads in thin sheets with high pushout and torque-out resistance- PAGES 4 and 5 Type SL...
