• • Prevents loosening caused by vibration, shock and thermal expansion
• • Seals against leaks and reduces risk of corrosion

Lockfast T42 Nutlock

Lockfast T42 Nutlock is a blue, medium-strength, general purpose threadlock designed for the sealing and locking of threaded fasteners, allowing for disassembly (using hand tools) at a later date. T42 prevents rust, corrosion, leakage as well as loosening from vibration or shock.  Particularly suited for less active substrates such as stainless steel and plated surfaces.  Typical applications can include 1/4″ to 3/4″ bolts on small engines, driveshafts, bearing cover cap screws, gearboxes, machine tools, presses, pumps and compressors, swing sets and furniture.

Directions For Use

1. For optimum performance surfaces should be clean and free of grease.
2. If the material is an inactive metal consider using activator.
3. Shake the product thoroughly before use. Apply several drops to the bolt & nut.
4. Assemble and tighten as required.
5. To prevent the clogging of the nozzle, do not let the tip touch metal surface during application.

Fixture Time vs. Substrate

There may be a difference in fixture speed and strength based on the substrate. As opposed to passive materials such as stainless steel or zinc dichromate, anaerobic adhesives will reach full strength more rapidly with active materials such as mild steel and brass.

For more information on strength of bond and cure time, please see the Lockfast threadlocker technical information sheet.

Disassembly and Clean-up

Remove with standard hand tools. In circumstances where hand tools do not work, use localised heat to bolt or nut, disassemble while hot. To remove cured product use a combination of solvent and abrasion such as a wire brush.
