Nut Manufacture Steps - 100% In-House

While there are not as many steps in the manufacture of a nut, each step is just as critical. If the nut fails, then having a perfectly manufactured bolt doesn't matter.

The steps listed below are some of the steps that a given nut goes through prior to being stamped with "ARP".

But you can be guaranteed every step happens under ARP's roof in the hands of an ARP employee!

1. Cutoff from wire or bar stock

2. Heat Treat

3. Forging

4. Threading

5. Shot Peening - to remove stress risers

6. Metal Finishing - Black Oxide coated, or in the case of Stainless, polishing

7. Packing - nuts are coated to prevent surface corrosion prior to packing and storage
