Threadlockers are a superior alternative to conventional lock washers, nylon inserts, and other mechanical devices. Threadlockers secure the entire fastener assembly against loosening from impact and vibration by filling the space between threaded metal parts. The threadlocker liquid or gel cures to form a strong adhesive bond and seal. Threads are also protected against leakage, preventing rust and corrosion.
