Permatex Medium Strength Blue Threadlocker

Permatex medium strength blue threadlocker is OEM specified. Blue is an all-purpose threadlocker ideal for all nut and bolt applications of 1/4 in. to 3/4 in., eliminating the need for stocking expensive lock nuts and lock washers. It locks and seals while preventing parts from loosening due to vibration, and it protects threads from corrosion, can be removed with hand tools for easy disassembly, and conforms to ASTM D 5363 AN0321 standards. Permatex medium strength blue threadlocker is offered in several sizes and available in a gel formula that provides "liquid-reliability" without drips, globs, mess, or waste.
