Vibra-Tite VC-3 Threadmate is one of the most versatile thread lockers available. An alternative to traditional liquid lockers, which cure to form a complex 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 adjustable, removable, and reusable.
- An acrylic polymer that damps and absorbs vibration
- Will not harden like anaerobic thread lockers
- Works with metal, wood, plastic (*see table), and more
- Fasteners are easily adjusted, removed and reused
- Works on fasteners of any shape or size, from tiny eyeglass screws to large construction bolts
- Works with internal or external threads
- Meets low out-gassing specifications (NASA SP-R-0022A, per ASTM E 595)
- Compatible with: ECTFE, EPDM, FEP, Nylon 6/6, PE, PEEK, PET, PFA, PP, PPS, PTFE, TFE, UHMW plastics.

Excellent shelf life
Parts coated with Vibra-Tite VC-3 can be stored indefinitely before use.
|
Versatile Adheres to ferrous and non-ferrous metals, most platings, wood, and plastic (see table) screws. |

Multiple reuses
Steady pressure and standard hand tools allow parts coated with VC-3 to be easily adjusted, removed, and reused. |
Minimizes galling / stripping Since Vibra-Tite VC-3 remains a thick, resilient, viscous resin, its cold flow properties actually minimize the galling or stripping of soft threads during reuse. |
Underwater installation Unlike anaerobic thread lockers, VC-3 can be air dried and installed into a mating part under fresh and salt water. |
Shake well before each use. Apply VC-3, a length of 1 to 1 ½ times the fastener diameter, filling threads 30-50%. Although material will be dry to touch within minutes, allow VC-3 to dry for at least 30 minutes (the longer, the better), depending on part size. Fasteners are then ready for assembly or to be stored for later use.
- From tiny eyeglass screws to huge construction bolts, Vibra-Tite VC-3 is ideal for fasteners of any size.
- Mounting ski / snowboard bindings, plates and inserts.
- RC models (Drones, Airplanes, Helicopters).
- Bolts on motorcycles.
