GREAT-LOCK Thread Locker: Superior Performance For Less

Threaded fasteners have been used for almost 2,000 years to fasten parts together. The metal threaded fasteners that are used today are much stronger than those used in the past, but they can easily become loosened by vibration and temperature change.

Threadlocker solves the problem of threaded fasteners coming loose by filling the gaps between the threads, and bonding them with adhesives. Threadlocker is used by mechanics and manufacturers on just about every piece of threaded material that is fastened.
