Loctite 222 is a low-strength, purple anaerobic threadlocker designed to lock and seal small threaded fasteners to prevent loosening caused by vibration, shock, and thermal expansion. It cures in the absence of air between close-fitting metal surfaces and allows easy disassembly with standard hand tools.
It is commonly used on small screws, bolts, and set screws in electrical equipment, instruments, machinery, and maintenance applications.
