Nylok® Blue Nylon Torq-Patch® Tuflok®

Prevailing Torque Locking Element

Nylok® Blue Nylon Torq-Patch® Tuflok® is a self-locking element comprised of nylon permanently bonded onto the threads of a fastener. When the Nylok® Blue Nylon Torq-Patch® Tuflok® is engaged, it creates a wedge between the fastener and mating part, compressing the nylon and creating metal-to-metal contact opposite the patch. 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.
