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.
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.

 Specifications:
