LOCTITE® 222 is designed for the locking and sealing of threaded fasteners which require easy disassembly with standard hand toolsThe product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration Particularly suitable for applications such as adjustment of set screws, small diameter or long engagement length fasteners, where easy disassembly is required without shearing the screwThe thixotropic nature of LOCTITE® 222 reduces the migration of liquid product after application to the substrate.
