Vibra-Tite VC-4
Vibra-Tite VC-4 exhibits similar performance to Vibra-Tite VC-3 except it contains a base solvent of Ethyl Acetate. VC-4 is one of the most versatile threadlockers available on the market. Unlike traditional liquid lockers which cure to form a hard bond, VC-4 is a blend of resins designed to remain flexible and absorb vibration. This unique difference makes VC-4 coated fasteners truly adjustable, removable, and reusable.

- Product Specifications
Description
- Ethyl Acetate base
- An acrylic polymer that dampens and absorbs vibration
- Will not harden like anaerobic threadlockers
- Works with metal, wood, plastic (See table below), 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
Features
- Excellent Coated Shelf Life: Parts coated with Vibra-Tite VC-4 can be stored indefinitely before use.
- Versatile: Vibra-Tite VC-4 adheres to both ferrous and non-ferrous metals, most platings, wood, and plastic* screws (*See table below).
- Creates a Reliable, Powerful Lock & Seal: With exceptional reliability, Vibra-Tite VC-4 holds parts in place even during extreme vibration and resists leakage by acting as a dam between mated threads.
- Offers Multiple Reuses: Using steady pressure and standard hand tools, parts coated with Vibra-Tite VC-4 can easily be adjusted, removed, and reused.
- Minimizes Galling/Stripping: Since Vibra-Tite VC-4 remains a thick, resilient, taffy-like “viscous resin,” its cold flow properties actually minimize galling or stripping of soft threads during reuse.
- Can be installed underwater: Unlike anaerobics, VC-4 can be air dried then installed into a mating part under both fresh and salt water.
Easy To Use:
Shake well before each use. Apply VC-4 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-4 to dry for 10-30 minutes (the longer the better), depending on part size. Fasteners are then ready for assembly or to be stored for later use.
Applications:
From tiny eyeglass screws to huge construction bolts, Vibra-Tite VC-4 is ideal for use on fasteners of any size.
Material Properties

| Reusability | Using steady pressure and standard hand tools, parts coated with Vibra-Tite VC-4 can easily be adjusted, removed, and reused up to 5 times. |
| Minimizes Galling/Stripping | Since Vibra-Tite VC-4 remains a thick, resilient, taffy-like “viscous resin,” its cold flow properties actually minimize galling or stripping of soft threads during reuse. |
| Engagement torque | Moderate |
| Breakaway torque | No distinct break; slow release as material cold flows |
| Standard coating length | 1 to 1 1/2 times diameter |
| Lead thread requirement | None |
| Thread Fill requirement | 30 – 50% of the thread root area |
VC Formula Plastic Compatibility
Note that all VC products are applied and dried on a fastener first. So if your fastener is metal, it can likely be installed into any substrate as the solvent has already evaporated.
