Loctite 222 - Threadlocker - 50ml

LOCTITE® 222 Threadlocker – Low-Strength Threadlocking Adhesive.

LOCTITE® 222 is a low-strength, purple anaerobic threadlocker designed to secure and seal small threaded fasteners while allowing easy disassembly with standard hand tools. It cures in the absence of air between close-fitting metal threads, preventing loosening caused by vibration, shock, and thermal expansion.

This threadlocker is ideal for low-strength applications where regular maintenance or adjustment is required, such as calibration screws, set screws, countersunk screws, and small-diameter fasteners. LOCTITE 222 also helps protect threads from corrosion and leakage, improving the reliability and service life of assembled components.
