Loctite 270 – Threadlocker

Loctite 270 is a high-strength, anaerobic threadlocker designed to permanently lock and seal threaded metal fasteners in demanding industrial and automotive applications. It cures in the absence of air when confined between close-fitting metal threads, forming a durable bond that prevents loosening caused by vibration, shock, and thermal cycling. It also protects threaded assemblies from corrosion, moisture, and fluid leakage, ensuring long-term reliability and safety.

Loctite 270 is ideal for securing bolts, nuts, studs, and threaded assemblies that are not intended for routine disassembly. It provides excellent adhesion to steel, stainless steel, brass, and other metal fasteners, making it suitable for heavy-duty machinery, pumps, compressors, gearboxes, motors, and automotive components. The cured adhesive distributes stress evenly across the threads, reducing wear and preventing fretting corrosion.

Once fully cured, Loctite 270 creates a permanent bond that generally requires localized heat and suitable tools for disassembly. It offers outstanding resistance to oils, fuels, hydraulic fluids, coolants, water, and many industrial chemicals, ensuring dependable performance in harsh operating environments.
