Loctite thread locker blue 242 is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces. It protects threads from rust and corrosion and prevents loosening from shock and vibration. Loctite thread locker blue 242 is particularly suited for applications on less active substrates such as stainless steel and plated surfaces; where disassembly is required for servicing.
