Product Description

The 3M 7010310189 is a general-purpose, medium-strength threadlocker sold under the Scotch-Weld TL42 line. It applies as a purple liquid and cures to lock threaded fasteners against loosening caused by vibration, shock, and corrosion. The medium-strength formula is designed for removability with standard hand tools, making it suitable for assemblies that require periodic disassembly and maintenance. It is used across mechanical, HVAC, plumbing, and industrial maintenance applications wherever threaded connections need reliable retention without permanent bonding. Each unit is sold as a single 1-litre container.

TL42 fits general maintenance and assembly work in both residential and commercial settings. It is appropriate for use on bolts, screws, studs, and other threaded fasteners subject to vibration or thermal cycling. Typical installers include HVAC technicians, pipefitters, millwrights, and maintenance mechanics who work on equipment requiring scheduled service. The purple color aids visual identification on treated fasteners before and during installation.
