LOCTITE® 222 – Low Strength Threadlocker for Small Fasteners

Secure Small Threaded Fasteners with Confidence
LOCTITE® 222 is a low-strength anaerobic threadlocker designed to prevent loosening caused by vibration while allowing easy disassembly with standard hand tools. It is ideal for small threaded fasteners made from metal, including adjustment screws, set screws, countersunk screws, and low-strength fasteners that require periodic maintenance.
The adhesive cures in the absence of air between close-fitting metal surfaces, creating a reliable bond that resists vibration, shock, and minor leakage while protecting threads from corrosion.
