Vibra-Tite VC-3 Threadmate Threadlocker, 250 mL Metal Can, Red Vibra-Tite VC-3 Threadmate is one of the most versatile threadlockers available on the market. An alternative to traditional liquid lockers which cure to form a hard bond, VC-3 is a proprietary blend of thermoplastic elastomer resins designed to remain flexible and absorb vibration. The combination of inert/non-reactive amorphous resins creates a tough, semi solid layer inside the threads of a mated joint. VC-3 damps the vibrational energy transferred between the threads of a mated fastener, preventing fastener loosening and loss of clamp load. These unique differences make VC-3 coated fasteners truly adjustable, removable, and reusable.
