I am awaiting the arrival of original used Ford axle nuts before trying again with my little torqueing project. Expect them by the end of the week. Have done a lot of research on the Internet to try to locate any source for a Grade 8 5/8” – 18 slotted nut. I found nobody who carries a Grade 8. Some carry a Grade 5. One supplier told me that this nut is no longer manufactured. This leads me to the conclusion that 5/8”- 18 nuts being sold today by old V-8 Ford parts suppliers are not Grade 8 unless they are very old stock. My obvious conclusion is that the ONLY way to go is to use the original Ford nut—no exceptions. In other words, unless you have the absolute assurance that a non Ford nut is a Grade 8, don’t use it. After I explained that his nut failed, the vendor who sold me the nut that failed is removing them from stock and will no longer sell them. He was appreciative of my letting him know.
