NYLOK® Blue Patch (TUF-LOK®)

Thread Locking and Sealing solutions from Lancaster Fastener

 

NYLOK® Blue Patch is a self-locking element comprised of nylon permanently bonded onto the threads of a fastener. When the NYLOK® Blue Patch 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® 180° Standard Blue Patch (TUF-LOK®)

 

This patch is applied to an area covering approximately 180° of the circumference of the thread. It offers excellent resistance to vibration in applications that require increased thread locking and re-usability.

NYLOK® 360° Optional Blue Patch (TUF-LOK®)

 

This patch is applied to an area covering the entire circumference of the thread. This process is suited to applications that require a re-usable high pressure seal against liquids or gas.
