High Demand Item – Frequently Reordered by Contractors
Solution 11 is a high-strength, single-component anaerobic red threadlocker. It cures in the absence of air between metal threads to form a permanent-grade lock that resists heavy vibration and shock. It’s built for fasteners up to 1 inch in diameter that you do not intend to remove during routine service.
Supplied as a red liquid; because it’s a high-strength grade, disassembly is difficult and typically requires applying localized heat. Sizes run from 10 ml bottles to 1-liter jugs, plus a 35 ml pump.
