Threadlocker Screw Glue | Product DescriptionProduct IntroductionOur threadlocker is a professional-grade anaerobic adhesive specially designed for locking and sealing metal threaded fasteners. It cures rapidly in the absence of air between tight metal surfaces, forming a durable bond that prevents loosening, leakage, rust and corrosion caused by vibration, shock and temperature changes. Widely used in automotive, motorcycle, machinery, home appliances, electronics and industrial equipment.Model Selection Guide243 Blue ThreadlockerMedium strength, oil-tolerant, removable with standard hand tools. General-purpose for most bolts, nuts and fasteners in automotive and machinery.271 Red ThreadlockerHigh strength, permanent locking. For heavy-duty, non-disassembly required bolts in engines, heavy machinery and high-vibration equipment.Key FeaturesAnaerobic Curing: Remains liquid in air, cures quickly between metal threads without oxygen.Anti-loose & Anti-vibration: Effectively stops screws from loosening under long-term vibration and shock.Leakproof & Sealing: Fills thread gaps to prevent gas and liquid leakage.Anti-rust & Anti-corrosion: Protects metal threads from rust, oil and chemical corrosion.Temperature Resistant: Stable performance from -55°C to 150°C.Easy Application: Single-component, no mixing required, convenient to use.Application Material: Metal screws, bolts, nuts, threaded fastenersHow to UseClean and dry the thread surfaces to remove oil, dust and impurities.Apply an appropriate amount of glue evenly on the external threads.Assemble and tighten the fasteners normally.Leave for 10–20 minutes for initial curing, full strength achieved after 24 hours.NotesKeep sealed in a cool, dry place away from fire and high temperature.Avoid contact with eyes and skin; keep out of reach of children.For high-strength red threadlocker, heating to 230°C+ is required for disassembly.
