LOCTITE® 243 is a medium strength blue threadlocking adhesive that seals and secures metal nuts, bolts and screws to prevent loosening due to shock and vibration.

LOCTITE® 243 is a general purpose threadlocker that provides a medium strength bond. LOCTITE® 243 works on all metals, including passive substrates such as stainless steel, aluminium and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g., motor oils, corrosion prevention oils and cutting fluid.
