Set screws keep COMING LOOSE
from your firearm?

Try a little VC-3 on the screw threads to LOCK ‘EM DOWN!

VC-3 is formulated differently than a typical threadlocker. It’s made of a composite resin that doesn’t harden, but stays soft to absorb the vibration caused by recoil and daily use. And, unlike the blue 242 threadlocker, it doesn’t break down and crack plastic. Created to withstand the vibration of tank engines and recoil, it’s a perfect solution for your long gun or sidearm.

What it does

  • As a firearm threadlocker VC-3 acts like a shock absorber, isolating the screw from the gun frame while dampening vibration, making it perfect for:
    • scope rings
    • sites
    • picatinny rails
    • laser guides
    • mounted pistol lights
    • custom grips
  • Prevents the screw from rotating loose, yet always remains flexible allowing it to be adjusted, removed, and reused.

Why it works

Vibra-Tite VC-3 Threadmate is one of the most versatile firearm threadlocker available on the market. Unlike traditional liquid lockers which cure to form a hard bond, VC-3 is a blend of resins designed to remain flexible and absorb vibration. This unique difference makes VC-3 coated fasteners truly adjustable, removable, and reusable.
