3M™ Scotch-Weld™ Threadlocker TL42 provides vibration, corrosion, and shock resistance for fasteners in assembled form. This blue anaerobic adhesive is dispensed as a single-component, medium viscosity product. This medium 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 TL42 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. 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 medium-strength adhesive loosens when needed with regular hand tools. Our 3M™ Scotch-Weld™ Threadlocker TL42 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 screws, bolts and nuts
  • Designed to cure and seal threaded assembles for a wide range of applications
