Have you searched Mc Master Carr? They will sale you any length of hex stock and carry a very large selection of nuts.
I will hand tap the hole to match the axle thread size / pitch, ThanksJim
That's a big hole to be hand tapping. And concentricity and squareness are quite important to make sure the nut seats hard against the frame or a washer. Since the internal thread does not have a bottom but goes all the way through, I would prefer and recommend you use a lathe to cut the nut threads. You can square or face the nut stock once mounted. The work will be more gentle and create smoother threads.Patrick HayesFremont CA
I found 1!https://straight-eight.com/product-category/fasteners-fittings-metric/nuts-fasteners-fittings-metric/m11/Also looks like ARP used to make them as a special order pack. Maybe if you contact them.-AJ
1 would look at some 4140.. Seems pretty versatile.. I had some shafts made up from my fiend and he uses a lot of it..
What about using smaller nuts and rethreading them rather that getting a specific alloy of hex stock. McMaster Carr and others sell extra wide and thick nuts in various alloys. Get one in 10mm , bore and tap.Pete
I wish I had a fiend….
Do you have the capability to thread at all? If so, you can set up the proper pitch, take out much of the stock and then run a tap through it on the lathe. Easy Peasey. Of course, being an airplane guy, I like 4130. Plenty strong and easy to machine.
I will have to grind a small inside tool. I
Thanks Chuck, I could give that a try on the M15 x 1.25 nut, I will have to grind a small inside tool.
I spent a few years in Fairview and I certainly enjoyed being inside during those winter days .
Not just any friend, but brilliant on top of it.. It would blow you away the stuff he does.. Here is one of the tools he bought a while back. It's only a 8 ft brake but weighs 40,000 lbs. His lathe came out of the closed down Nuke plant in Oregon..
