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, nuts are for installation into stainless steel sheets.
Type CLA aluminum nuts are recommended for use in aluminum sheet with a hardness
of HRB 50 or less on the Rockwell "B" scale.
Type H and HN (non-locking) and Type HNL (locking) nuts (page CL-6) self-clinching nuts.
Type SMPS self-clinching nuts are for installation into ultra-thin sheets. They feature a lower profile
and can be mounted closer to the edge of a sheet than other self-clinching nuts.
Type SL self-locking nuts are designed with a unique and economical locking feature, which meets demanding locking performance requirements.
