Product Information

The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.

Particularly suitable for applications on less active substrates such as stainless steel and plated surfaces, where disassembly with hand tools is required for servicing. The thixotropic nature of blue Loctite 242 reduces the migration of liquid product after application to the substrate.

  • Prevents loosening of metal fasteners caused by vibrations


  • Loctite 242
  • Anaerobic Threadlocker
  • Sizes - 10ml, 50ml, 250ml and 1 litre bottles
