Nylok® Blue™ Nylon Pellet & Strip

Prevailing Torque Locking Element

NYLOK blue™ nylon pellet & strip is a self-locking element comprised of nylon permanently imbedded into the threads of a fastener. The pellet is a drilled hole with a plug of oversized nylon wedged into the hole. The strip is a milled slot with a string of oversized nylon wedged into the slot. When the pellet & strip are engaged it creates a wedge between the fastener and mating part compressing the nylon and creating metal to metal contact opposite the element. This metal to metal contact results in a positive resistance to vibration and loosening. Since nylon has great memory characteristics, this locking element can be reused several times.

Nylok^® Torq-Strip^® self-locking elements are permanently embedded in the threads of a fastener. When mating threads are engaged, the tough, resilient Blue nylon element is compressed and a counter-force is created to establish a much stronger contact and positive resistance to vibration and loosening.

A Nylok^® Torq-Strip^® self-locking element 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 (M1.2) can be processed and these Nylok self-locking elements can be applied with equal effectiveness to larger diameter fasteners.
