LOCTITE® 221™ is a low-strength, anaerobic threadlocker designed for locking and sealing threaded fasteners that require disassembly with standard hand tools. It cures in the absence of air between close-fitting metal surfaces, preventing loosening and leakage due to shock or vibration. It is particularly suited for applications like set screws, small diameter, or long engagement length fasteners.
