  • Sonlok® Pre-Applied Threadlockers

    SONLOK® pre-applied to threaded parts from a unique coating that converts ordinary fasteners into self-locking and self-sealing fasteners. Dry to touch, SONLOK® Pre-Applied threadlocker become an integral part of the fastener-and stay inert until parts are used. During the assembly process, SONLOK® Pre-Applied is activated by assembly forces, releasing anaerobic adhesive which locks and seals parts securely. Use SONLOK® Pre-Applied products successfully, without solvents, in extreme temperature and pressure environments to lock and seal against air, steam, most fluids and lubricants.
