Head Studs and Nuts

There was a post a couple of days ago asking "where to get original type head studs and nuts". The discussion that followed didn't really answer the question. I posted a reply, but I may not have done it correctly. So please consider the following:

Original type studs and nuts are available online from several sources. Search for "stud 18-6066", "nut B6064", etc. In fact, many N parts cross to early Ford car and truck parts. Mac's, Eckler's, and C & G are good sources. I prefer to use original type parts when possible, especially engine parts. I lightly honed my cylinders and used Hastings rings for a 239 V8 in my 8N (half of the set) because I preferred cast iron over chrome. They broke in easily and are running great. It uses very little oil. The head studs and nuts I found are correct in form, fit and function and required no modifications. Just wanted to make sure this information is available to those who prefer original type parts. Thanks.

Thank you Slim. I did see your post the other day and thought it was good advice. Henry Ford was a good business man. He knew it was cheaper to use the same parts across the line as he could.

Thanks slim sometimes good info gets passed up in the shuffle...

I posted on the head studs and nuts and bolts the other day and listed the info on where to buy from, what was asked. I listed sources, assumed you could follow the links and continue with your own homework. I don't know what you are talking about when you say "...the discussion...really didn't really answer the question...". Copied from my previous post:

"I replied with sources on the 'other site'. Get studs from SUMMIT RACING and hex nuts at McMaster-Carr. Everyone seems to be going with head bolts these days. Here's a 7/16-14 x 7/16-20 x 3.00 stud, Grade 8, from SUMMIT RACING. It was the first place I looked so there may be others like allensfasteners. Note length is 3". OEM specifies 3 at 2.9" and 15 at 2.78" so if you must, grind off the 7/16-20 end that accepts the hex nut. Use an old one to compare with. Torque is different for nuts and bolts. The UNC (coarse) end, 7/16-14 always goes into cast iron. The UNF (fine) end, 7/16-20 accepts the hex nut. Hope this helps you.

SUMMIT is found in the url LINK below. McMaster-Carr and Allensfasteners can be found on their web site shown above.

FWIW & FYI: FORD engineered bolt lengths at odd fractional sizes, and are no longer made. Ford & Ferguson wanted no more than 1 or 2 threads protruding from a bolt or stud so as not to snag the farmer's clothing. The industry today manufactures bolt lengths in standard sizes such as 3.0". You can choose from 2.5", 3.0", or 3.5" but you won't find any odd lengths anymore at 2.8" or 2.9" except for the select parts that Dennis Carpenter makes. Thus TOH's post about ensuring the length is correct was covered with my statement to "...COMPARE WITH YOUR OLD..." stud. Grind off excess length at the top 7/16-20 stud end and if needed the 7/16-14 end on the engine block side.

SUMMIT RACING 7/16 STUDS

Good morning, Tim. I've enjoyed reading your very informative posts for some time now. I'm sorry I didn't make it clear when I said the discussion didn't really answer the question. It didn't. The man asked where to get the original type studs and nuts. To me, that means just like original - same length, grip length, etc. You stated "Ford engineered bolt lengths at odd fractional sizes, and are no longer made" and "you won't find any odd lengths anymore at 2.8" or 2.9" except for the select parts that Dennis Carpenter makes". Yes, you will find the odd length studs 2.78, 2.90, 3.09, 3.15 and the original type cad plated nuts if you'll just follow the links below. And there are other sources besides Mac's.

I wasn't trying to one-up anybody or ruffle anybody's feathers; just trying to answer the question. Hope this helps.

OK- I looked in my MACS, SUMMIT, and BRATTONS (LeBarron-Bonney is out of business)catalogs first but didn't see them so I will add them to my list now. hard copy catalogs nowadays don't seem to offer much -not all items are listed. Great information, thanks for the correction.
