Product Information

T90 Pre-assembled Threadlock

Lockfast T90 Pre-assembled Threadlock


Lockfast T90 Pre-assembled Threadlock is a high-strength, very low viscosity threadlocker designed for the locking of preassembled threaded fasteners.  Due to its very low viscosity, T90 is able to seep (wick) between engaged threads, eliminating the need to disassemble.  Prevents rust, corrosion and leakage as well as loosening from vibration or shock.  Recommended for instrumentation screws, electrical connectors and carburettors. Particularly suitable for filling of porosity in welds, castings and powdered metal parts.


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.
