Blue Medium Strength Threadlocker 242, 36 mL Bottle

Loctite 492140 is Loctite 242—a medium-strength, medium-viscosity, thixotropic, anaerobic threadlocker engineered for locking and sealing metal fasteners that require later disassembly with standard hand tools; it cures in the absence of air between close-fitting metal threads to resist loosening from shock and vibration, protect against rust and corrosion, and deliver quick fixture on steel, brass, zinc-plated, and stainless fasteners.
