Loctite 243 is a medium strength general-purpose thread locker which secures and seal bolts, nuts and studs to prevent them from loosening due to vibration. 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 like industrial oils, engine oils, corrosion-prevention oils and cutting fluids.
Cures in the absence of air to provide a tough retaining medium for threaded parts
Tolerates slight contaminations of industrial oils, e.g. engine oils, corrosion prevention oils and cutting fluid
Prevents loosening of vibrating parts, e.g. pumps, gearboxes and presses
Permits disassembly for servicing using normal hand tools
