50ml Thread Locker Thread Sealant Glue 222 - 290 Screw Locking Adhesive Anti‑Loose Anti‑Corrosion Anaerobic Glue for Bolts Nuts

LOOLIFL Threadlocker Screw GlueThis anaerobic thread locker is specially developed for metal threaded fasteners. It fills tiny gaps between threads and cures when oxygen is isolated. It realizes screw anti‑loosening, sealing & leak‑proof, rust and corrosion resistance. With excellent high‑temperature resistance, it prevents screws from loosening caused by long‑term equipment vibration.Multiple Models for Different Application222 (Low Strength): For small precision screws, easy to disassemble. Ideal for household appliances and instrument tiny threads.242 (Medium Strength): General removable grade for ordinary bolts and nuts, convenient for maintenance disassembly.243 (Medium Strength Oil‑Resistant): Works even with slight oil contamination on threads. Perfect for auto parts.262 (Medium‑High Strength): Strong locking force, needs tools for disassembly. For fasteners under heavy vibration.263 (High Strength Oil‑Resistant): Semi‑permanent locking, great resistance to vibration and impact.271 (High Strength): Permanent locking. For threads that do not require frequent disassembly.272 (High Temp & High Strength): Designed for high‑temperature working conditions, suitable for engine components.277 (For Large Threads): Specially for large‑size bolts and heavy‑duty machinery.290 (Penetrating Type): High fluidity, seeps into pre‑assembled thread gaps for re‑locking existing screws.Product Advantages✅Anti‑Vibration & Anti‑Loosening: Resist equipment vibration to stop self‑loosening✅Leak‑Tight Seal: Fill thread gaps to prevent liquid and gas leakage✅Anti‑Corrosion & Anti‑Rust: Block moisture and air to protect metal threads✅Heat Resistance: Working temperature:‑54℃~230℃ for various working environments✅Anaerobic Curing: Cures only inside oxygen‑free metal gaps, no drying‑up inside bottleInstructions for UseClean threads thoroughly to remove grease and dust.Apply proper amount of glue onto threads.Tighten screws into place.Partial curing takes several minutes. Allow 24 hours for full curing to reach maximum strength.ApplicationWidely used in auto repair, mechanical equipment, engineering machinery, hardware assembly, instruments and meters, for locking and sealing bolts, nuts and metal threaded fasteners.NotesFor metal threads only. Keep away from children. Avoid contact with eyes and skin. Rinse immediately with plenty of water if contact occurs.
