10ml Anaerobic Threadlocker Adhesive 222 242 243 262 271 290

Keep fasteners locked tight with this professional-grade anaerobic threadlocker and sealing adhesive. Available in eight popular formulas (222, 242, 243, 262, 263, 271, 277, and 290), this 10ml screw lock compound is designed for metal threaded assemblies across a wide range of industrial, automotive, and mechanical applications. Each formula cures in the absence of air (anaerobic curing), providing a strong, vibration-resistant bond that guards against loosening, rust, and corrosion.

Made in Mainland China.

Formula Guide

• 222 – Low Strength: Low viscosity formula ideal for frequently disassembled fasteners and easily cut metals. Removes easily with standard hand tools.
• 242 – Medium Strength (Universal): Thixotropic viscosity for locking and sealing M6–M20 threads. Removable with ordinary tools; offers a degree of lubricity for precise clamping.
• 243 – Medium Strength (Oil-Tolerant): Fast curing on inert and mildly oily surfaces. Suitable for M20 and smaller threads; easy to disassemble.
• 262 – High Strength: Excellent chemical and environmental resistance on most metal surfaces. Thixotropic viscosity; permanent locking for threads up to M20 under extreme conditions.
• 263 – Medium-to-High Strength: Suitable for most metal surfaces with strong chemical resistance. Permanent locking and sealing for M20 threads with outstanding rust and corrosion resistance.
• 271 – High Strength, Low-to-Medium Viscosity: Designed for permanent locking and sealing of threads up to M36.
• 277 – High Strength, High Viscosity: Superior chemical resistance; permanently locks and seals threads up to M36. Prevents rust and corrosion; can be disassembled with heat and tools.
• 290 – Medium-to-High Strength, Ultra-Low Viscosity: Penetrates pre-assembled fasteners without disassembly — ideal for preventive maintenance and wicking applications.

Safety & Handling

For workplace safety guidance when handling adhesives and chemical sealants, refer to OSHA's Chemical Hazards resources. Always work in a well-ventilated area and wear appropriate protective gloves and eyewear.

Frequently Asked Questions

Q: What is the difference between the threadlocker grades (e.g. 222 vs. 271)?

A: The grades differ primarily in strength and viscosity. Low-strength formulas like 222 allow easy disassembly with hand tools, making them great for small or frequently serviced fasteners. Medium-strength options like 242 and 243 balance holding power with removability. High-strength grades such as 271, 277, and 262 are intended for permanent assemblies and require heat or specialized tools for disassembly. Grade 290 is ultra-low viscosity, designed to wick into already-assembled fasteners without taking them apart first.

Q: How long does the anaerobic threadlocker take to cure?

A: The adhesive achieves handling strength (fixation) in approximately 60 minutes under normal conditions and reaches full cure strength within 24 hours. Curing occurs in the absence of air between two metal surfaces — ensure surfaces are clean and free of excess oil (unless using an oil-tolerant formula like 243) for best results.

Q: Can this threadlocker be used on non-metal surfaces?

A: This anaerobic adhesive is specifically formulated for metal-to-metal threaded assemblies. Anaerobic adhesives require metal ions to initiate curing and may not perform correctly on plastics, ceramics, or other non-metallic substrates. For non-metal applications, a different adhesive type is recommended.

Q: Is the 10ml bottle enough for multiple applications?

A: Yes. Only a small drop or bead is needed per fastener, so a single 10ml bottle typically provides enough adhesive for numerous applications, depending on the thread size. The compact bottle also features a screw-lock cap for easy storage between uses.
