TL42 is a general purpose, medium strength, thixotropic anaerobic threadlocker. The product cures when confined in the absence of air on close-fitting metal surfaces.
3M TL42 is formulated to lock all metric and imperial nuts and bolts, preventing vibration loosening and leakage through the threads. TL42 is designed for use on parts where disassembly with hand tools for servicing is required. The thixotropic nature of the product prevents run off, dripping and migration after assembly. Once applied, parts slip together easily, lubricated by the adhesive. TL42 prevents corrosion of assembled parts.
