3M™ Scotch-Weld™ Threadlocker TL77 provides vibration, corrosion, and shock resistance for fasteners in assembled form. This red anaerobic adhesive is dispensed as a single-component, medium viscosity product. This high removal torque anaerobic adhesive offers a long open time and 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, helps seal 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. Our 3M™ Scotch-Weld™ Threadlocker TL77 is effective for locking, vibration resistance, sealing, and bonding threaded assemblies. Places where it is useful include machine tool access bolts, hydraulic system bolts, gear box/driveshaft bolts, bearing cover cap screws, countersunk screws, and conveyor roller bolts.

Suggested applications
  • Threadlocking of larger screws, bolts and nuts, and coarse threaded parts
  • Designed to cure and seal threaded assembles for a wide range of applications
