What bolts and nuts are you using for B/RB OEM chrome valve covers? I've tried to find stainless/chrome hardware and so far I've found nothing but flange style bolts and nuts in stainless or chrome, not the captive washer style hardware. Thoughts?

I’m using stainless steel studs from ARP.

What are you using for nuts?

I would imagine a acorn style nut. I found these but not polished stainless. Should be able to find it if you dig deeper.

I should have been more specific, my bad. What OEM style nuts and bolts are you using for OEM B/RB chrome valve covers? I have spent over three hours looking for something and so far all my digging has gotten me is a dry hole!

I don't have the chrome covers, but Classic Industries (among others) sell the OEM style bolts - $ 10.99 each !
Studs & nuts for the ends, plus the bolts, $30 on Ebay.

For non-resto covers, I use studs & nuts all around.

ACE Hardware here has real chrome plated fasteners. They do look very very nice despite the stiff price tag.

Likely going to be a task to find anything with a captured washer at a hardware store.

Grainger has lots of hardware if you have one locally, but they lean toward selling in bulk quantities on some things. Cool if you need 100 of something, but not so cool if you need only 20.

Last year I bought some misc stuff from Bolt Depot that I could not find locally. https://boltdepot.com/Catalog If you want to use studs for your covers buy some individual socket set screws from here and put SS or chrome plated nuts on them.

Found the bolts, can't find the studs and nuts. Got an item number or link?

I bought Allen threaded studs here. Sometimes they are called 'running thread'.

Socket screws are also called grub screws as well.

I forgot about Fastenal. We have one here, but it's way on the south side of town by the airport otherwise I'd use them more often. I dislike having to order small things like fasteners as the shipping is often as much or more than the actual items, but sometimes it's that or go without.

ARP stainless steel nuts, they come in a kit. I’m looking for my packaging.

Thanks to everyone who replied. I have enough info to move forward.

I'll have to go and dig thru the bolts , valve covers have been off for almost 19 years now and I don't remember if the chrome covers on my BB a body had painted or chrome .. I think they were chrome though ??
Where's Rhinodart when you need him.

My original 383 had stock painted bolts on my factory chrome valve covers, but I have seen chrome bolts too...

I really appreciate all the effort going into this post. Now I'm not going to say I'm 100% right but if I have it correct, the B/RB engines with stock chrome covers were the 1965 426 standard, the 1967 440 in the GTX, and the 383 in the 1969 Dart 383. There may be others, I don't know.

A trip through the 1965 parts book under 9-3-28 shows different numbers for the 426 standard valve covers so I am going assume they are chrome. Like wise the 1967 parts book listing is for high performance which I would believe are the chrome covers. The 1969 parts book calls out specific covers for the B2/L2 which I assume are the chrome covers.

But in no listing I can find chrome bolts or nuts listed, just one version in '65 of both that I assume are the unplated hardware. In fact in '67 and '69 I can't even find the bolts listed, just the nuts.

So based on Jim's comments I am going to decided on a path for plated or stainless hardware and go from there. Thanks to all again for the effort.

I'm pretty sure my '67 GTX 440 had plated VC bolts - but that was decades ago.
It was an untouched original car.
Painted fasteners for them would have driven me nuts (pardon the pun)

So one thing nobody asked was when the engines were painted at the engine plant did they have standard steel valve covers and bolts on them then changed out for the chrome covers afterwards?

My guess is that the VCs were masked off, like the Hemis were.
I can't imagine swapping stuff back & forth would be efficient in mass production.

I don't know. Looking at the picture of your Dart it looks like the lower front fastener is a bolt rather than a stud and a nut. I'm not even going to go down that rabbit hole. I have enough trouble keeping Dave straight!

Yes, all valve cover fasteners are bolts, none were a stud and nut when I bought the car in 1978...
