Its low viscosity lets it penetrate threads easily; once cured it forms a durable bond that prevents loosening from vibration and secures assemblies of steel, brass, stainless steel and other metals. This formula gives a balance of strong retention with practical work times for assembly and repair.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly does this threadlocker set on different metals?\u003c\/h3\u003e\n\u003cp\u003eCure (fixture) times depend on substrate: brass and steel cure faster than stainless steel. These fixture times are measured on steel, brass and stainless steel under typical conditions; full cure strength develops over time and with reduced clearances between mating parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel fixture time: about 10 minutes\u003c\/li\u003e\n  \u003cli\u003eBrass fixture time: about 5 minutes\u003c\/li\u003e\n  \u003cli\u003eStainless steel fixture time: about 15 minutes\u003c\/li\u003e\n  \u003cli\u003eFull cure increases with close-fitting threads and room temperature\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat kinds of fasteners and environments is this product suitable for?\u003c\/h3\u003e\n\u003cp\u003eLOCTITE 271 is optimized for metal fasteners and works well on bolts, studs and machine screws up to roughly 1 inch in diameter. It tolerates slight contamination from industrial oils, making it useful in pre-serviced or mildly oily assemblies.
