## Description

" Convenient, Portable & Effective 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.

MILITARY GRADE ADHESION This high-strength thread locker is tested to the lot requirements of Military Specification Mil-S-46163A. MIL-SPEC (Military standard or Military-SPEC) adhesive are products that meet or exceed the US defense standard, a measure of quality set to standardize the expectations of all products supplied to the US Military. Each lot is also tested by the ASTM (American Society for Testing and Materials), a body of skilled personnel that specializes in testing materials and generating standards of quality.
