LOCTITE® 225

Features and Benefits

This brown, 1-part, medium-viscosity anaerobic threadlocker prevents threaded connections from loosening due to shock and vibration.
LOCTITE® 225 is a brown, medium strength, medium-viscosity liquid threadlocker. The anaerobic adhesive cures when confined in the absence of air between close fitting metal surfaces. It is designed for the locking and sealing of threaded fasteners, which require disassembly with standard hand tools at room temperature.
