Nuts! Head nuts.... Acorn? Stainless?
I have been looking for stainless steel acorn nuts to fit the head studs but all I find are fake covers that go over the original nuts.
Does anyone sell proper acorn nuts in stainless for the flatheads head studs? Or in chromed brass? I have spent some time looking with no luck..... I guess I could make them if I really wanted too.... |

I think Flathead Jack did. They are/were pricey!
Looks like Red's may have them: http://reds-headers.com/html/fh_parts.html http://reds-headers.com/html/external.html Last edited by JSeery; 04-24-2019 at 09:22 AM. |

Re: Nuts! Head nuts.... Acorn? Stainless?
"General" commercial available SS will not withstand the torque values needed for flathead torques.....I have some 304SS 7-16-20 NF SS Acorn nuts (Maybe 40psi max torque) but have not and will not use them on a Flathead. With that said there "MAY BE" a company offering a "hardened" SS Acorn nut (like ARP) not sure BUT if so they will not be cheap and unless the seller can provide me with certs or mill test reports I would not trust them!!!!
NOTE: The above mentioned McMaster Carr items are the same as I have and IMO I would not recommend. Max torque value is 36ft/lb dry & 27ft/lb lubed. They are the standard commercial variety!!! Last edited by rockfla; 04-24-2019 at 09:38 AM. |

Re: Nuts! Head nuts.... Acorn? Stainless?
"Could"......is another word "possibly". Its a you're gamble with you're motor. Factoring in the head cycles and the "recommended" values I'm not that big of a gambler!!! Just my .02 worth!!!

I would check with Red's and see what the torque values are for the ones they have.

Re: Nuts! Head nuts.... Acorn? Stainless?
According to the Red's page, theirs are "Chrome plated" which would indicate to me that they are a steel nut that is chrome plated?????, I see no mention of SS. I'm with JSeery, I would see what Red's charges for theirs IMO???

Re: Nuts! Head nuts.... Acorn? Stainless?
I'm with 19Fordy, go with the chrome plated covers and save yourself $$ and grief!! Torquing the heads is somewhat important....think I read this somewhere!

No fake nut covers for me. That just seems wrong.

Re: Nuts! Head nuts.... Acorn? Stainless?
I'm running covers on my 8ba that I got from Patrick's (before he went sideways). Used a bit of silicon to make sure they stayed on. No issues and IMO they don't look like covers.

Re: Nuts! Head nuts.... Acorn? Stainless?
My local hardware store carries the covers, a dab of silicone and they have been on for 3 years with no problems.
