Loctite 222 is a single-component, anaerobic low-strength threadlocking adhesive. When confined between metal threads, it cures to a hard thermoset plastic that locks and seals fasteners. Ideal for small diameter screws and bolts made of low-strength metals like aluminum or brass, it provides reliable vibration resistance and easy disassembly with hand tools.
