Hold It Australia T22 SCREWLOCK

Low Strength for Easy Disassembly - 50ml

Description: HOLDIT AUSTRALIA T22 Screwlock is a low strength, anaerobic thread locking compound, ideal for locking threaded fasteners that require disassembly with standard hand tools. It performs excellently on aluminium, steel, plated, stainless steel, and special alloy parts. T22 is characterized by its good temperature and solvent resistance.


T22 is specifically formulated to lock and seal small screws (less than ¼”), including set screws with long engagement lengths.
