A blue colour, all purpose, medium strength threadlocker formulated for locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. It cures when confined in the absence of air between close fitting metal surfaces. It locks bolts and nuts up to 20 mm diameter, preventing loosening due to vibration, and sealing against leakage and corrosion. It can work on lightly oiled surface and is chemical resistant, resisting fuels, lubricants and most industrial liquid and gases.
