The original NYLOK® BLUE® nylon self-locking, self-sealing and reusable fastener is still the industry standard.

A NYLOK BLUE PELLET or TORQ-STRIP self-locking element can be applied to your own fasteners, or ready-to-install self-locking fasteners. It can be supplied to meet your specifications. Screws as small as #00-90 (M1.2) can be processed and these nylon self-locking elements can be applied with equal effectiveness to larger diameter fasteners.
