222 243 271 Threadlocker Anaerobic Glues Anti Loose Screw Glues Fastening Quickly Cured Thread Locking Agent Sealant for Screws

243 & 271 Threadlocker Anaerobic AdhesiveProduct DescriptionProduct Overview243 blue and 271 red threadlocker are professional anaerobic adhesives specially designed for locking and sealing metal threaded fasteners. They cure in the absence of air between metal surfaces to prevent loosening, leakage and rust caused by vibration, ensuring long-term stability of mechanical assembly.Key Features1. Professional Anaerobic Curing TechnologyThe glue remains liquid in the bottle and cures rapidly when confined between metal threads and isolated from air. No heating or UV irradiation required, forming a tough, durable polymer layer that fills all thread gaps.2. Dual Strength Options243 Blue Threadlocker – Medium StrengthOil-tolerant formula works well on slightly oily surfacesRemovable with standard hand tools for future maintenanceGood temperature resistance, reliable for general applications271 Red Threadlocker – High StrengthPermanent locking and sealing for high-load assembliesHigh temperature resistance and heavy anti-vibration performanceRequires heat for disassembly, suitable for permanent connections3. Strong Anti-Loosening & Anti-VibrationEffectively prevents nuts and bolts from loosening under long-term mechanical vibration, widely used in automobiles, motorcycles, engines, machinery and industrial equipment.4. Anti-Rust & Sealing ProtectionProvides excellent sealing against liquids, gases, oil and moisture. Protects threads from rust, corrosion and abrasion, extending service life of fasteners.5. Wide ApplicationSuitable for all metal threaded parts: engine bolts, motorcycle chassis screws, bicycle components, household appliances, industrial machinery, automotive repair and hardware assembly.Application GuideClean and dry thread surfaces; remove oil, dust and rust for best results.Apply appropriate amount of glue evenly on the threads.Assemble nuts and bolts to the required torque.Allow full curing for maximum strength (full cure in 24 hours).Warm TipsKeep out of reach of children.Avoid contact with eyes and skin. Rinse with water if accidental contact.Store in a cool, dry place away from heat, fire and direct sunlight.Seal tightly after use to prolong service life.
