Designed for use on threaded assemblies continuously exposed to extreme temperatures, Henkel’s Loctite 2422 and Loctite 2620 anaerobic threadlocking adhesives withstand heat and stress to 650°F. Loctite 2422 is a medium-strength threadlocker for applications where disassembly with hand tools is required. High-strength Loctite 2620 requires short-term exposure to temperatures over 650°F to remove the nut and bolt with hand tools. Anaerobic pastes that solidify when confined between close-fitting metal surfaces in the absence of air, both adhesives prevent loosening from shock and vibration. They are available in syringe packages.
