When you’re working with parts that need regular dismantling – retention of bearings on shafts and in housings, for example – you need LOCTITE® 641. This medium strength anaerobic retaining compound cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.
