High-viscosity, high-strength threadlocking paste for locking and sealing threaded fasteners to prevent loosening from shock and vibration. Specially formulated for applications where temperature resistance up to 343°C (650°F) is required.
When you need a threadlocker for applications subjected to severe shock and vibration – especially where you also need extreme high temperature resistance – LOCTITE® 2620 is a great choice. This thixotropic threadlocking paste cures when confined in the absence of air between close fitting metal surfaces to prevent loosening and leakage.
