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
- Maximum thread size M36
- Breakaway torque on M10 bolt 26 Nm
- Fixture time for steel 10 minutes
- Fixture time for brass 5 minutes
- Fixture time for stainless steel 10 minutes
- Service temperature range: -55 to +180°C
- P1 NSF Reg. No: 123000
