Prevents nuts and bolts from loosening with vibration Fills and seals threads completely to help stop corrosion, rust and leaks Eliminates the need for lock washers and other locking components Engineered for use on larger bolt sizes and coarse threaded parts Red, high removal torque Long open time anaerobic adhesives that cure quickly Helps keep production equipment up and running 3M™ Scotch-Weld™ Threadlocker TL77 provides vibration, corrosion and shock resistance for fasteners in assembled form. Our red, high removal torque anaerobic adhesive is dispensed as a one-component, medium viscosity product. This long open time anaerobic adhesive cures quickly in the absence of air when parts are assembled. Our 3M™ Scotch-Weld™ Threadlocker TL77 hardens and seals threaded assemblies to resist vibration and prevent loosening or leakage of secured fasteners. Applying this adhesive to fasteners before tightening seals out moisture and prevents corrosion. Application is fast and easy with just a targeted squeeze of the bottle. Engineered for use on larger bolt sizes and coarse threaded parts, the anaerobic formulation begins to cure quickly into a polymer that seals, secures, and retains. An activator can be used for even faster cure or larger gap sizes. The high strength adhesive is only removable through high heat application.
