Loctite 2701 – Threadlocker

Loctite 2701 is a high-strength, low-viscosity anaerobic threadlocker designed for the permanent locking and sealing of threaded metal fasteners. 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 in demanding industrial environments.

Loctite 2701 is specially formulated for use on inactive metals such as stainless steel, zinc-plated steel, and other plated fasteners, where rapid and reliable curing is essential. It is ideal for securing bolts, nuts, studs, and threaded assemblies subjected to heavy loads and continuous vibration. Its low-viscosity formulation allows the adhesive to flow easily into fine threads, ensuring complete coverage and consistent locking performance.

Once cured, Loctite 2701 provides a permanent bond that typically requires localized heat and suitable tools for disassembly. It offers excellent resistance to oils, fuels, hydraulic fluids, coolants, water, and many industrial chemicals, making it suitable for harsh operating conditions.
