Loctite® 262 is a high strength threadlocker that helps you permanently anchor studs, cylindrical parts, bearings and bushings. Replace shaft locking devices such as keyways and splines. Provides greater break-loose torque than Class 5 Interference fits. Seals against leakage and corrosion; unaffected by liquid fuels, lubricants and most chemicals. Temp. range: -65º to 300ºF (-54º to 149ºC). We recommend this high strength loctite for high tensile and vibration such as such as Bali song and automatic knife, and guns screws. This is extreme duty Loctite®. We recommend Loctite® 262 to clean and prep your screws and parts before assembly.
