242 Medium Strength Blue Threadlocker Anaerobic Adhesive 10ml

242 Medium Strength Blue Threadlocker – Reliable Metal Fastener Security

Keep bolts, screws, and metal fasteners firmly in place with this 242 Medium Strength Anaerobic Threadlocker Adhesive. Engineered for a wide range of hardware applications, this blue threadlocker formula cures between mating metal surfaces, locking fasteners securely while remaining removable with standard hand tools when needed — making it the ideal choice for maintenance, assembly, and repair work.

Made in Mainland China.

Key Features

• Medium Strength Formula: Provides a firm, reliable hold on metal fasteners while still allowing disassembly with standard tools — no permanent bond.
• Anaerobic Curing: Cures in the absence of air between close-fitting metal surfaces for a strong, gap-filling seal.
• Anti-Corrosion & Heat-Resistant: Withstands working temperatures up to 150°C, protecting threads from corrosion and oxidation.
• Vibration Resistant: Absorbs vibration and prevents fastener loosening under dynamic loads and mechanical stress.
• Leak & Sealing Protection: Effectively fills micro-gaps to prevent fluid or gas leakage around threaded connections.
• Thixotropic Viscosity: Stays exactly where you apply it — no dripping or running — for precise, mess-free application.
• No Volatilization, No Pollution: Clean, stable formula that does not off-gas or contaminate surrounding surfaces.
• Long Shelf Life: Approximately 24 months of usable shelf life when stored properly.

How to Use

1. Clean and degrease mating metal surfaces thoroughly before application.
2. Apply a small drop of threadlocker to the fastener threads.
3. Assemble the fastener immediately and tighten to the desired torque.

Frequently Asked Questions

Q: What is a medium strength threadlocker and when should I use it?

A: A medium strength (242-type) threadlocker is an anaerobic adhesive designed to lock threaded metal fasteners securely in place while still allowing removal with standard hand tools. It is ideal for screws, bolts, and fittings that may need to be periodically serviced or adjusted, such as those in machinery, automotive assemblies, or plumbing connections.

Q: Is this threadlocker permanent?

A: No — this is a medium strength formula, meaning it provides a strong, vibration-resistant hold but can be disassembled using standard hand tools when needed. It is not a permanent bond like high-strength (red) threadlockers.

Q: How long does this threadlocker take to cure?

A: Anaerobic threadlockers begin to cure once air is excluded (i.e., when the fastener is assembled). Initial handling strength is typically achieved within 1–2 hours, with full cure reached within 24 hours depending on temperature and metal type.

Q: Can I use this on non-metal surfaces?

A: This 242 medium strength threadlocker is specifically formulated for metal surfaces. It may not cure properly on plastic, rubber, or other non-metallic materials. Always use on compatible metal fasteners for best results.

Q: How many pieces are included per order?

A: This product is available in 1, 3, or 5 bottle options — each bottle contains approximately 10ml of threadlocker adhesive. Screws and fasteners are not included.
