LOCTITE® 242
LOCTITE® 242 is a medium-strength, medium-viscosity threadlocker for applications requiring disassembly with standard tools. It is effective on less active substrates and resists loosening due to vibration or shock.
LOCTITE® 242 Features:
- Medium strength and viscosity
- Thixotropic formulation for reduced migration
- Fast fixture time
LOCTITE® 242 Applications:
- Threadlocking on metal fasteners up to M36
