Threadlocker Screw Glue - Product DescriptionProduct OverviewThis anaerobic threadlocking adhesive is specially designed to lock and seal metal bolts, nuts and fasteners. It cures in the absence of air between tight metal threads, forming a durable, rigid bond that prevents loosening caused by vibration, shock and thermal expansion. It also provides excellent sealing against rust, corrosion and fluid leakage, widely used in automotive, motorcycle, machinery, hardware and electrical equipment.Key FeaturesAnaerobic Curing: No mixing required, cures automatically when confined between metal threads without air.Anti-Loose & Anti-Vibration: Effectively stops screws from loosening under long-term vibration and impact.Sealing & Anti-Rust: Fills thread gaps, seals out moisture, oil and dust to prevent rust and corrosion.High Strength & Durability: Forms a hard thermoset bond with strong holding torque, stable performance.Temperature Resistant: Wide working temperature range from -50℃ to 150℃, suitable for various environments.Easy Application: Needle tip bottle design for precise dispensing, clean and convenient to use.Color-Coded Strength: Purple (Low), Blue (Medium), Red (High) for different assembly needs.Model Selection GuideBlue 243 (Medium Strength): Removable with standard tools, oil-tolerant, general-purpose for most assemblies.Red 272 (High Strength): Permanent locking, requires heat for disassembly, suitable for heavy-duty and non-adjustable fasteners.How To UseClean and dry the screw threads to remove oil, dust and impurities.Apply 1-2 drops of threadlocker evenly to the threaded area.Assemble and tighten the fastener as required.Allow to cure fully; initial strength in minutes, full bonding in 24 hours.Warm TipsFor best results, ensure threads are clean and oil-free before use.Keep sealed when not in use to prevent premature curing.Avoid contact with eyes and skin.
