3M Scotch-Weld Threadlocker, TL42 Series, Medium Strength, Blue (Equivalent to Loctite 242/243)

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 seals 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.
