Overview

Flush head studs are pressed into a drilled or punched hole until the head sits flush with the sheet. The serrated head locks against rotation and the sheet flows into the undercut, giving a permanent, high-strength threaded stud in sheet as thin as 1 mm.

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