L243 Threadlocker (Medium Strength)

Akfix L243 is a medium strength thixotropic anaerobic thread locker. The product cures when confined in the absence of air between close-fitting metal surfaces.


  • Formulated to lock all metric and imperial nuts and bolts
  • Prevents vibration loosening and leakage through the threads
  • Slightly oil tolerant; it will bond some ‘as received’ parts, but best results are obtained with clean substrates.
  • The thixotropic nature of the product prevents run off, dripping and migration after assembly.
  • Typically used on mounting bolts, housing screws, etc.
  • Prevents corrosion of assembled parts.
