CLS-832-1 PEM

PEM brand self-clinching nuts install permanently in aluminum, steel or stainless steel sheets. CL SELF-CLINCHING NUTSSELF-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. S/SS/CLA/CLS/CLSS nuts H (non-locking) and HNL (locking) provide load-bearing threads in thin nuts have threads that provide high sheets with high pushout and torque-out pushout and torque-out resistance - resistance - PAGES 4 and 5 PAGE 8 SP, PEM 300 nuts provide strong SH hard panel nuts install into thin, load-bearing threads in stainless steel harder, high strength steel materials - sheets as thin as .030/0.8 mm - PAGE 8 PAGES 4 and 5 SMPS/SMPP nuts are for thinner PEM RT free-running locknuts are sheet/close-to-edge applications - free-running until clamp load is induced. A PAGE 9 modified thread angle on the loaded flank provides the vibration resistant locking Material and finish specifications - PAGE 9 feature- PAGE 6 Installation - PAGES 10 and 13 SL self-locking nuts are designed with a unique and economical TRI-DENT locking feature, meeting 3 cycle locking Performance data - PAGES 14 - 17 performance requirements - PAGE 7 Many PEM self-clinching nuts in this bulletin are dimensionally equivalent to nuts manufactured to NASM45938/1 specifications. Consult our Marketing department for a complete Military Specifications and National Aerospace Standards guide (Bulletin NASM) on our website. Screws for use with PEM self-clinching locking fasteners should be Class 3A/4h fit or no smaller than Class 2A/6g.
