The thread locking torque performance of Type PL and PLC PEMHEX® self-clinching fasteners is equivalent to applicable NASM25027 specifications. A nylon hexagonal element provides a reusable, non-metallic prevailing torque thread lock. The strong knurled collar receives the installation force and resists torque. The spin resistance of the knurl greatly exceeds the torque that can be exerted by the self-locking feature. As the knurled collar is embedded in the sheet, the undercut cavity beneath the collar is filled with displaced sheet material, thereby captivating the fastener in the sheet.
The color blue for fastener locking elements is a registered trademark. Unified fasteners have a blue nylon locking element and metric fasteners have a black nylon locking element.PL.jpg
Type CFN broaching fasteners are available for thinner sheet, close-to-edge applications. The locking element provides prevailing torque to eliminate loosening of mating threaded hardware.CFN.jpg
