Prevailing Torque High Temp Locking Patch

Nytemp® self-locking patch is comprised of high temperature polymer permanently bonded onto the threads of a fastener. When the Nytemp® patch is engaged, it creates a wedge between the fastener and mating part, compressing the polymer and creating metal-to-metal contact opposite the patch. This metal-to-metal contact results in a positive resistance to vibration and loosening. Since this polymer has great memory characteristics, the locking element can be reused several times.
