LOCTITE LOCK 'N' SEAL 243 – 5ML

Keep threaded fasteners secure with LOCTITE Lock 'N' Seal 243, a fast-acting threadlocker and sealant designed to prevent loosening caused by vibration and movement.

The blue, medium-strength formulation is suitable for a wide range of metal threaded assemblies and provides a secure bond while still allowing components to be removed using normal hand tools when required. LOCTITE explains that threadlockers fill the gaps between mating threads and cure to prevent fasteners working loose.
