Lockfast T42 Nutlock Medium Strength Threadlocker

Lockfast T42 Nutlock is a medium-strength blue threadlocker designed to lock and seal threaded fasteners while allowing future disassembly using standard hand tools. Ideal for preventing loosening caused by vibration, shock, and thermal expansion, it also seals threads against leaks and helps protect against rust and corrosion.

Specially formulated for use on stainless steel, plated metals, and other less active substrates, T42 provides a reliable locking solution for a wide range of engineering, automotive, industrial, and maintenance applications. Typical uses include bolts, gearboxes, pumps, compressors, machine tools, bearing cap screws, driveshafts, furniture, and general mechanical assemblies.
