Vibra-TITE VC-3 Threadmate Threadlocker, 30 ml Red Bottle with Brush Cap — Vibration-Resistant, Removable

Vibra-TITE VC-3 Threadmate is a red, brush-top threadlocker that locks and seals threaded fasteners by bonding through viscosity to resist loosening from vibration.

VC-3 Threadmate is a versatile acrylic thread locking coating formulated to stop fasteners from backing out under shock and vibration while still allowing later adjustment with hand tools. Supplied in a 30 ml bottle with a brush cap, it dries to the touch in seconds and allows parts to be assembled in minutes. The product adheres to most metals, platings, plastics and wood, and it works on both internal and external threads without the need for aggressive surface preparation — simply remove visible oil, grease or dirt for best performance.

How quickly can I assemble parts after applying VC-3?

VC-3 becomes tacky almost immediately and practical assembly can begin within minutes. Full handling strength and solvent resistance improve over time, but once the coating is set to the touch you can join parts without long waits.

• Dries to the touch in seconds under normal conditions
• Ready for assembly typically within a few minutes
• Faster curing with good airflow and temperatures below 130°F (54°C)

Will this threadlocker work on different materials and finishes?

Yes — VC-3 was designed to bond via a high-viscosity acrylic formula that performs on a wide range of substrates. It adheres to ferrous and non-ferrous metals, many platings, plastics and even wood screws, making it useful across multiple applications.

• Compatible with metal, plated surfaces, plastics and wood
• Suitable for both internal (nuts) and external (bolts, screws) threads
• No special primers required for most common finishes

How does VC-3 behave under vibration and reuse situations?

Instead of forming a rigid bond, VC-3 creates resistance through viscosity so mated threads resist loosening in high-vibration environments. At the same time it allows parts to be adjusted or removed with standard hand tools and can permit multiple reuses when handled correctly.

• Prevents loosening from shock and vibration by filling thread gaps
• Allows removal and reassembly several times with steady torque
• Provides a slow, fluid release rather than a sudden breakaway

What storage, shelf life and chemical resistance can I expect?

VC-3 has a generous shelf life when stored properly and offers useful resistance to many common solvents, water and salt water. It also acts as a partial corrosion barrier between mated threads.

• Indefinite shelf life under ideal storage conditions
• Resistant to water and salt water; offers partial solvent resistance
• Cured form provides resilient plastic barrier between threads

Who this is for: Vibra-TITE VC-3 Threadmate is aimed at technicians, hobbyists, maintenance professionals and manufacturers who need a dependable thread-locking coating that works across many materials and sizes — from precision electronics and eyeglass screws to large construction bolts. It’s especially useful where vibration resistance, quick assembly, and the ability to later adjust or reuse fasteners are priorities. The 30 ml brush-cap bottle makes it convenient for bench work, repairs, and field service jobs where controlled, consistent application matters.
