Self-clinching nuts suitable for restrictive design envelopes

PEM® type SMPS™ self-clinching nuts from PennEngineering® are suitable for fastening in ultrathin metal sheet applications in which design envelopes may be restrictive and space for attachment hardware may be limited.

Installing permanently in steel or aluminum metal sheets as thin as 0.025 in., their 0.145-in. edge-of-sheet to center-of-fastener distance enables close-to-edge mounting on a panel. The 0.220-in. dia. and 0.065-in. height combine for a low profile.

A serrated clinching ring prevents the fastener from rotating after installation.
