70 Chevelle Seat Adapter Bolt

Please see the attached pictures. I am needing to replace some of these bolts in my factory bucket seat adapters due to rust damaging the threads.
Anyone know of a source for these bolts? What is this style of bolt called? I've tried flat head bolt, Blind head bolt and nothing comes up.
Any help will be appreciated. This bolt is fine and can be reused.

I'm going to post this in my Project thread as well.

Thanks

Chris

Re: 70 Chevelle Seat Adapter Bolt

I'm thinking "Elevator Head Bolt" ?.

https://www.google.com/search?q=elev...Ymiq6eDwyIHh8M

I bought some for use on modifying my welded in hatch hinges on my 74 Nova to allow it to be a bolt on type hinge. Seems to me I got them at the local Ace brand hardware store in the little pull out bins ?.

Re: 70 Chevelle Seat Adapter Bolt

If this welds to the floor, why not just tack weld a regular bolt?

We no longer have an Ace Hardware near us anymore. I did see that the bolt is very close to an elevator bolt. The head seems a little on the thin side. I'm afraid that in a collision (God for bid) that it wouldn't hold to the floor.

You are very correct. The adapters do weld to the floor. That is my fall back solution, and I'd use grade 8 bolts. But I'll try and go the OEM route first. Just wish I could remember what the letters on the bolt head stood for. I know its for the company that manufactured the bolt.

Thanks guys for the replies.

X2. A regular grade 8 bolt would give more surface area to weld the bolt to the bracket. Once it painted black nobody will be able to tell difference. Actually Iím not sure the originals are grade 8 as I snapped one off first time I was bolting my seat to it. Was already welded to floor so I just ended up drilling through the remaining bolt and then tapped it. Just run a regular original seat bolt down through the top. Been working that way for over 15 years.

Check AMK's site. It takes a while to get used to searching but they have almost every known automotive fastener.

Re: 70 Chevelle Seat Adapter Bolt

Thanks for the input guys. After looking at all suggested sites and photos, I think I'm just going to use a grade 8 bolt and weld those in.
Thanks for the AMK suggestion. I know NPD has some listings for the Master Kits and I have one for the engine already. I now need to compare and see who will be the least expensive for the rest of the car..
