LOCTITE® 271™ is a red, low viscosity, methacrylate-based threadlocking adhesive with high strength. With steel fixture time of 10 min, brass 5 min and stainless steel 15 min. Can tolerate slight contaminations of industrial oils. Suitable for all metal fasteners. Breakaway torque on M10 bolts of 26 Nm. Fluoresces under UV light. Perfect for temperatures between -65°F – 360°F (-54°C – 182°C).

LOCTITE® 271™ is designed for the permanent locking and sealing of threaded fasteners. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. LOCTITE® 271™ adds 3,000 PSI holding power on slip and press fit assemblies. Typical applications include the locking and sealing of large bolts and studs (up to M25 ). MILITARY GRADE ADHESION
