Overview

Self-clinching nuts press into a punched or drilled hole. The sheet flows into the undercut and the knurl stops rotation, giving strong, permanent, reusable threads in thin sheet with a flush reverse side.

Full dimensions, preferred lengths and installation / push-out / torque-out performance data are shown in the datasheet below, taken from the self-clinching fasteners catalogue.
