McMaster's site shows their stover nuts as 'medium strength' and not to be used in high vibration environments, and has me second-guessing the original plan. Don't know if castle nuts are considered lighter duty than standard nuts

Old thread bump - trying to source bolts based on the length of the shank/grip/unthreaded portion of the bolt is proving more difficult than I would have thought. Usually I get everything from an awesome local fastener supply, but while they have what I need, it's only in black phosphate/oil covered. Too bad, since I can just pick bolts up out of the bin and measure in person. The CAT stuff posted above is badass, the fact that they spec out their bolts in 1/4" increments showing 'grip' length of each - unfortunately it's all oil coated/black phosphate as well. Called earlier to verify - no zinc or yellow zinc for their 3/4" fine bolts. Seems like as soon as they're not coated in oil, they rust pretty quick.
12 point stuff is out, since I just welded in a bunch of the Deuling Design nut capture plates (only on the bolt head side, so the bolt can't rotate). Looking for hex head, 3/4" fine bolts with a grip/shank length of 3.25, 3.5 and 3.75. Waiting to hear back from McMaster and Fastenal supposedly - no one I've called seems to know anything other than total bolt length. What am I missing?
Lastly, I was planning to use castle nuts and cotter pins for all link/shock bolts. Torque to spec, line up cotter pin hole and pin, and be as maintenance free as possible. Although in terms of usually bolts not being torqued as much as they should, not sure if that's just extra labor when I could just stover nut and make sure everything's truly torqued to spec

MS21250-12 (3/4-16")
The go to standard for high strength 12 Pt. bolts. Rated to a minimum of 180k psi tensile strength. Bolt length is determined by the non-threaded portion know as the "grip". The thread length is 1.036 regardless of grip size. Sold in 1/8" increments, 2.00, 2.125,2.250 etc..

And how do you know the cotter key being lined up is the correct torque? You can easily get enough turns on a nut to get a cotter key but not be in the same place as started with.
Seems like extra work to just using top locks. Add nordlocks if you want.
I had the same problem on a batch of fine thread 1/2" I bought from Grainger a couple of weeks ago."Min Thread Length" fucked me when it had an extra 1/4-3/8" over what I wanted. I'm curious what you find out.
no they are harder to find replacements or nuts for, easier to cross thread, our usage isn't really a "high" vibration environment. Yeah it can happen but ti's not super common. More of a lack of torque spec issue then a fine or coarse thread issue imo.

I don't know if there's enough meat on the 12pt head to grind off

If someone chooses to do this, make sure the plater is familiar with plating heat treated parts. You need to do a post-plating bake process to ensure the part doesn't get hydrogen embrittlement. If it's bad the bolt can crack just sitting in the box.
DesertPOS is absolutely right. I bought my link hardware through McMaster, and the bolts had way more thread on them than the minimum spec
Because that's the stock Jeep size.
It's all the XJ's fault.
Unless the bolt gets loose, or the friction force is overcome. If shear didn't matter no one would care about grip length.
how in the fuck did i know you would have a link from mcmaster ... ahhahahaahahaIf anyone needs a bit to open a hole from 9/16 to 5/8 or 3/4, these bits are the absolute shit. They work like a charm, last forever, and produce a nice surface finish and a round hole. They aren't cheap however.

I theory you shouldn't have to. I brought this up before and was promptly shut down. Sometimes theory doesn't = reality.
my problem with these are some holes i could only drill through from one side. could i go through both sides or am i missing how these work. because it said drill distance was only like 1.5 inches. maybe i am missing somethingIf anyone needs a bit to open a hole from 9/16 to 5/8 or 3/4, these bits are the absolute shit.
