ND Patch® Hi-Temp
The ND Patch coating process produces a completely dry product that is fused to the fastener and is ready to use right out of the box. ND Patch performs immediately upon assembly with no curing time required.
Description:
- ND Patch Hi-Temp maintains its torque performance through temperatures as low as -70°F (-56°C) and as high as +500°F (+260°C).
- ND Patch Hi-Temp is generally applied to a minimum of 2-3 threads back from the end of the fastener with 4-6 threads of coverage to assure ease of starting the nut/bolt assembly.
- ND Patch Hi-Temp can be applied to virtually any fastener, from very large construction bolts to tiny cellular phone and computer screws.
- How ND Patch Hi-Temp works: When a fastener coated with ND Patch Hi-Temp is mated to its corresponding hole or mating fastener, the material is compressed. This compression creates a dam-like action on the opposite side of the coated fastener creating very strong metal-to-metal contact. When ND Patch Hi-Temp is fully seated, it forms a positive lock that will not loosen, even under extreme vibration. This dam-like action also creates a positive seal to be used to prevent leakage.
- As with all of our pre-applied products, ND Industries can apply Patch Hi-Temp to your fasteners at any one of our regional service centers, or we can supply you with fasteners already coated with ND Patch Hi-Temp.

Features:
- Retains Full Strength: ND Patch Hi-Temp process involves no drilling or milling, so there is no loss of the fastener's strength or hardness and no troublesome burrs or chips.
- Saves Money: ND Patch Hi-Temp saves money by pins, or castellated nuts. ND Patch Hi-Temp is also less expensive than applying bottled thread locking compounds at the point of assembly.
- Saves Time: ND Patch Hi-Temp can be automatically fed through standard bowl feeders without the fear of material coming off.
- Chemical Resistant: ND Patch Hi-Temp will not dry, shrink, or otherwise be effected when exposed to commercial solvents, alcohol, gasoline, oil, caustic soda, jet fuel, etc.
- Reusable: Fasteners coated with ND Patch Hi-Temp can be re-used repeatedly without damage to the threads. ND Patch Hi-Temp is particularly resistant to deformation, which makes it ideal for repeated use.
- Saves Effort: During the ND Patch Hi-Temp process, camera systems are used to verify the parts are coated exactly to customer's specifications. This often removes a secondary sorting operation at the end customer.
- Fast Turn-Around: The ND Patch Hi-Temp process produces a complete, non-chemically reactive, ready to use product. The ND Patch Hi-Temp performs immediately upon assembly. There is no cure time required.
