Pre-Applied Vibra-Tite® VC-3®


Vibra-Tite VC-3 is designed for use on internal and external threads of virtually any material or finish. Fasteners with VC-3 pre-applied by ND Industries arrive dry to the touch and ready for installation. Unlike many other pre-applied threadlockers, VC-3 does not require heat for its application process, which reduces the chance of degradation of the fastener or its finish.

Product Information

How It Works

Vibra-Tite VC-3 prevents fastener assemblies from loosening due to shock and vibration. It is a solvent solution of acrylic polymers that acts as a shock absorber, dampening vibration and preventing fastener assembly thread rotation. VC-3’s unique formulation allows fasteners to be adjusted with standard hand tools, yet still maintain anti-vibration abilities.


Vibra-tite VC-3 adheres to both ferrous and non-ferrous metals, most platings, wood, and nylon, PPE, or PP plastics. Use on fasteners of any size or configuration.

Excellent Shelf Life

When in a cool and dry environment, parts coated with Vibra-tite VC-3 can be stored indefinitely before use.

Reliable, Powerful Lock & Seal

With exceptional reliability, Vibra-tite VC-3 holds parts in place even during extreme vibration and resists leakage by acting as a dam between mated threads.


Using steady pressure and standard hand tools, parts coated with Vibra-tite VC-3 can easily be adjusted, removed, and reused.

Minimizes Galling/Stripping

Since Vibra-tite VC-3 remains a thick, resilient, cold flow resin, its properties actually minimize galling or stripping of soft threads during reuse.

Chemical Resistance

Offers resistance to most solvents (acts as a partial corrosion barrier) with total resistance to water and salt water.

Other Benefits

  • Saves Time: Fasteners coated with Vibra-Tite VC-3 can be automatically fed through standard feeding devices.
  • Saves Money: Eliminates the need for costly lock washers, cotter pins, or castellated nuts. Moreover, Vibra-Tite VC-3 is less expensive than applying bottled threadlockers at the point of assembly.
  • Quality Control: Pre-Applied Vibra-Tite VC-3 parts are coated to specification, insuring consistent performance unlike bottled products.
  • Reduces Fatigue: Vibra-Tite VC-3 greatly reduces the need for retightening.


  • Pre-applied Vibra-Tite VC-3 is dry to the touch and ready for immediate use with no cure time.
  • Vibra-Tite VC-3 is a soft material and does not require any lead threads.
  • As with all our pre-applied products, ND Industries can apply Vibra-Tite VC-3 onto your fasteners at any one of our regional service centers, or we can supply you with fasteners that contain a pre-applied Vibra-Tite VC-3.
  • Vibra-Tite VC-3 can also be purchased for manual application (bottled product) from our Vibra-Tite Division.
  • * Recommended for Nylon, PPE & PP plastics only. ** Can be stored indefinitely when in a dry, cool environment.

Vibra-Tite VC-3 Competes With

  • N/A – Vibra-Tite VC-3 is a ND Industries exclusive product.


From tiny eyeglass screws to huge construction bolts, Vibra-tite VC-3 is ideal for use on fasteners of any size. VC-3 can serve as an alternative to ND Patch when low installation torques are required along with the need for adjustability and reusability.
