Well, both catalogs, 58-68, 60-70, show the same information for nut 7725, which is 5/16-24. But I will note that both studs, -58 and -65 show the same threaded spacer being used,52605-58... and the nut for the later stud is 3/8-24.DeltaElite wrote: ↑Mon Aug 08, 2022 4:16 pm ...
Looks like this is made out of unobtainium.
What does the 60-70s catalog say in regard to 52602-58? What nuts are associated to it in this catalog? 5/16-24 or 3/8-24 ?
Having said all that, @RooDog is correct, both studs are 3/8-24 so both catalogs are wrong for the nut listed. You need nut 7800.
