Self-Locking Element

The Nylok® Blue® Torqe-Patch® reusable self-locking element can be applied to virtually any type of nut and enables manufacturers to use a shorter bolt to make assemblies lighter. In the patented process, the blue nylon powder is permanently spray bonded onto the threads and can be applied with patch coverage from 180 to 360 degrees to any grade standard nut from as small as #10 (M5). The tough resilient blue nylon patch element is compressed as the mating threads are engaged, and a counterforce is created to establish a much stronger metal-to-metal contact that provides positive resistance to vibration and loosening, while still allowing the locknuts to be adjusted or reused if needed.
