A better way to lock bolts

By Paul Dvorak | June 1, 2009

The Nylok Blue Patch self-locking element is permanently spray bonded onto fastener threads. Engaging mating threads compresses the resilient blue nylon patch to generate a counterforce stronger that metal-to-metal contact and resistance to vibration and loosening.

The Nylok Blue Patch self-locking element is permanently spray bonded onto fastener threads. Engaging the mating threads compresses the resilient blue nylon patch to generate a counterforce stronger that metal-to-metal contact and resistance to vibration and loosening.

Small nylon patches on bolts provide features that “lock” it in place. For example, Nylong, from Nylok, Macomb, Mich, applied to a bolt thread creates a counter force that pushes the screw against its mating part, locking it and making other locking devices unnecessary. The same self-locking fastener can be reused several times without significant loss of locking ability. In addition, the device can stop leakage and works on any kind of threaded fastener. The materials also prevent vibration loosening in many applications. The material comes in several variations. For instance, Precote fastener adhesive and Scotch-Grip coatings are assembly activated making them well suited for industries that call for high-speed assembly. When micro capsules in the fastener adhesive rupture during assembly, a released liquid starts a chemical reaction. After an appropriate curing time, the fastener keeps its clamping load for the life of the assembly.
