Poly-Lok® is today’s most advanced, most reliable prevailing torque type self-locking fastener. And it’s all due to the unique polyester patch material that is more resilient, has higher strength, and can be reused more often with higher retained torque values than any other patch material.

Even the Poly-Lok manufacturing process is unique. The patch material is applied by a patented process of consistent amount, controlled as never before possible with this type of locking method. Thanks to this engineered proprietary control of patch size and location, dependable prevailing torque performance is achieved consistently from part to part. This exclusive Poly-Lok patch area control capability allows us to produce non-standard torque values custom tailored to your requirements; a control not attainable with spray-on patch methods. It all adds up to extra-reliability and dependability in almost any threaded fastening application.

The versatility and locking characteristics of the Poly-Lok patch open up a whole new range of fastener applications. From the aerospace to automotive market, engineers everywher are finding out how well Poly-Lok self-locking fasteners can solve their assembly problems.
