Metlok Private Limited offers Thread Locker for Locking and Sealing Threaded Fasteners. Metlok Private Limited is an ISO 9001: 2000 certified company. Thread Locker for Locking and Sealing Threaded Fastener or My-T-Lok ®350 is medium strength thread locker. Because of its low viscosity and capillary action, it wicks between engaged threads and eliminates the need to disassemble prior to application. The Thread Locker for Locking and Sealing Threaded Fasteners cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. It can also fill porosity in welds, casting and powder metal parts. These are used to lock set screw and grub screws as a final setting point.
