Mechanical Locking/Thread Sealing

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.

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.

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.
