Lockfast T22 Screwlock


Lockfast T22 Screwlock is a purple, low strength, low viscosity (thixotropic) screwlock designed for the sealing and locking of threaded fasteners, which may require easy disassembly with standard hand tools.  Ideal for small diameter screws or long-length fasteners where damage may occur upon disassembly.  Suitable for watch, instrument and small electronic component manufacturers.  Will produce a stronger bond when applied to larger threaded parts due to the greater surface area.  Cures in the absence of air, between close-fitting, threaded parts and prevents leakage or loosening from vibration and shock.


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.
