Colour: Blue

Overview:

Bond It Trade Glue Monster A43 Blue Threadlock is a medium strength anaerobic thread-locking adhesive designed to lock and seal threaded fasteners while still allowing later disassembly with standard hand tools. It is ideal for preventing loosening caused by vibration and shock on assemblies such as hydraulic system bolts, gearbox fixings, machine guards, brackets, and general engineering fasteners on plant and construction equipment.

The formula is oil tolerant, making it suitable for “as received” parts with a light film of oil, and its non-drip, medium viscosity consistency helps with clean, controlled application on fine to medium pitch threads. Once cured, it helps resist rust and corrosion within the thread, providing a reliable long-term hold for maintenance and repair work where secure fastening is essential but future servicing is likely.

Bond It Trade Glue Monster A43 Blue Threadlock 25ml – Key FAQs

• What is A43 Blue Threadlock used for?

  • It locks and seals threaded fasteners to help prevent loosening from vibration, while still allowing disassembly later using the correct tools.

• Can it be used on oily threads?

  • Yes, it’s oil tolerant and suitable for direct application to lightly oiled components, which can reduce the need for extensive pre-cleaning.

• How quickly does it set?

  • Handling strength is typically achieved in under 15 minutes at around 20°C, with full strength reached after 24 hours.

• Is it a high-strength thread locker?

  • No, it’s medium strength, intended for fixings that may need to be removed for servicing or maintenance.

• Does it help prevent corrosion?

  • Yes, it helps prevent rust and corrosion on threaded assemblies once cured, improving long-term reliability.

• Is it suitable for stainless steel fasteners?

  • Bond strength can be substantially lower on stainless steel and may not work on some grades without an activator, so suitability should be checked first.

• Can it be used on plastics or rubber parts?

  • It’s designed for metal bonding. If used near engineering plastics or rubbers, test first to confirm compatibility and performance.

• Are there any systems it should not be used in?

  • It’s not recommended for oxygen-rich systems and should not be used with chlorine or other strong oxidising materials.

Important Notes

• Not recommended for use with accelerators.

• Cure speed depends on temperature and bond gap (smaller gaps and warmer conditions generally cure faster).

• Store upright, sealed, and protected from frost and direct sunlight.

• Always read the latest Technical Datasheet prior to first use to confirm suitability and application guidance.
