Overview

High strength studs have a hexagonal, serrated head that gives much higher torque-out and push-out than standard flush head studs. Use them for heavy loads in thicker sheet.

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