I think the confusion was caused by the fact that there are varying descriptions of the 1365067 nut in various GM references I have. I expect that the 5/16" thick and phosphate finish came from one reference and the 11/32" and zinc came from another. However, it's very possible that the specs for the nut changed over time and that's the reason for the differences.
One thing that does surprise me, though, is that GM considered the 1365067 a "heavy duty" nut. Usually, "heavy duty" nuts are distinguished from "standard" nuts by greater thickness and/or larger wrench size for a given thread size. However, standard 3/8-24 nuts are 5/16" thick. So, the 1365067 at either 11/32" or 0.314" would actually be thinner than a standard nut and at 9/16" across-the-flats it's the same as a standard nut. So, why would GM then consider it a "heavy duty" nut?- Top
