Permatex Medium Strength Threadlocker Blue Formula is an all-purpose threadlocker ideal for all nut and bolt applications 6mm to 20mm. Eliminating the need for stocking expensive lock nuts and lock washers, this threadlocker locks and seals while preventing parts loosening due to vibration. It also protects threads from corrosion and is removable with hand tools for easy disassembly. Applied as a liquid or gel, threadlockers are superior to conventional lock washers, nylon inserts, and other mechanical devices because they secure the entire fastener assembly against loosening from shock and vibration by filling the space between threaded metal parts, curing to form a tough, adhesive bond and seal.
