3M™ Scotch-Weld™ thread locker TL42 provides vibration, corrosion and shock resistance for fasteners in assembled form. Our blue, medium removal torque anaerobic adhesive is dispensed as a 1-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™ thread locker TL42 hardens and seals threaded assemblies to resist vibration and prevent loosening or leakage of secured fasteners.
