Self-locking Fasteners

We are the famous Importer, Supplier and trader of self-locking fasteners in New Delhi, Delhi, India. The thread locking performance of Type PL PEMHEX self-clinching fastener meets the applicable standards of NASM25027. 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. 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.
