About the Vibra-Tite VC-3 Threadmate VC Threadlocker

Vibra-Tite VC-3 is a powerful locking and sealing coating for threaded fasteners that works on the principle of “friction through viscosity.” It utilizes a blend of acrylic resins to prevent fasteners from loosening — even under extreme vibration. Designed for use on external and internal threads of metallic and some plastics fasteners, Vibra-Tite VC-3 dries to the touch within minutes of application and coated parts are ready for assembly in just a few minutes. Pre-cleaning of parts is not required except for wiping off any visible oil, grease, or dirt for optimal performance.

Common Applications for Vibra-Tite VC-3 Threadlocker

From tiny eyeglass screws to huge construction bolts, Vibra-Tite VC-3 is ideal for use on fasteners of any size. Vibra-Tite VC-3 adheres to ferrous and non-ferrous metals, most platings, wood, and plastic screws.

Instructions for Using Vibra-Tite VC-3 Threadmate

Be sure material is well mixed before applying. Apply Vibra-Tite VC-3, with standard coating length 1.5 times the diameter of the part and to achieve 30% to 50% thread fill. While Vibra-Tite VC-3 dries to the touch within minutes, the part should be given at least 30 minutes to dry before assembly.

What makes VC-3 different?

  • An acrylic polymer that dampens and absorbs vibration
  • Will not harden like anaerobic threadlockers
  • 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, in accordance with ASTM E 595)
ColorRed (custom colors can be manufactured dependent on quantity.)
SolventMethyl ethyl ketone
Cured formResilient plastic
Shelf lifeBottled: 5 Years from date of manufacture.
Applied: Indefinite.
Chemical resistanceOffers resistance to most solvents (acts as a partial corrosion barrier)
Dries for use10-30 minutes, depending on part size.
Drying method for bulk productionBest achieved using considerable airflow in addition to temperature not exceeding 130˚F
Operational temperature range-65˚F to 165˚F (-54˚C to 74˚C) For other temperature applications, please contact us
ReusabilityUsing steady pressure and standard hand tools, parts coated with Vibra-Tite VC-3 can easily be adjusted, removed, and reused up to 5 times.
Minimizes Galling/StrippingSince Vibra-Tite VC-3 remains a thick, resilient, taffy-like “viscous resin,” its cold flow properties actually minimize galling or stripping of soft threads during reuse.
Engagement torqueModerate
Breakaway torqueNo distinct break; slow, fluid release as material cold flows
Standard coating length1 to 1 1/2 times diameter
Lead thread requirementNone
Thread Fill requirement30 – 50% of the thread root area
