The original NYLOK® BLUE® self-locking, self-sealing, reusable fastener exceeds industry standards.







The NYLOK BLUE PATCH™ self-locking element is permanently spray bonded onto the threads of a fastener. When mating threads are engaged, the tough, resilient blue nylon patch element is compressed and a counterforce is created to establish a much stronger metal-to-metal contact and positive resistance to vibration and loosening.

A NYLOK BLUE PATCH (known as TUF-LOK® in Europe) self-locking patch can be applied to your own fasteners, or ready-to-install self-locking fasteners can be supplied to meet your specifications. Screws as small as #00-90 (M1.0) can be processed and NYLOK BLUE PATCH self-locking elements can be applied with equal effectiveness to large diameter fasteners.
