Looking for a source of hardened axle nuts for a 1940 rear axle. I was installing the rear driver's side hub when I went to torque the axle nut to 200 ft/lbs. the nut stripped. I only got to 175 ft/lbs when the nut began to turn. These are brand new nuts from one of the vendors many of us use. When I purchased them I asked if they could take 200 ft/lbs of torque and was told that they hadn't received any complaints and the manufacturer of the nuts supplied most of the well-known early ford parts vendors.
This picture shows the nut after letting go.
The next picture shows the axle threads after running a 5/8-18 die over the threads. I tried the other new nut and this one never made it past 150 ft/lbs.
I know I can't be the only one who has come across this problem so if any of you have a good source for quality axle nuts please let me know. By the way 200-220 ft/lbs is the recommended torque value for this axle. Thanks
