A threadlocker is an anaerobic adhesive used on threaded metals that cures at room temperature in the absence of air. The adhesive completely fills the gaps between mating threads to lock and seal the threaded assembly.

LOCTITE® Threadlockers come in a wide variety of strengths and specialty formulations, including permanent and removable threadlockers.
