Original Battery Hold Down Clamp

I would like know that is the length of hold down bolt shown in the photos.

One inch in length with a .875 dia. captured washer.

Thanks for the information on the bolt.

Here's a couple of photos from my 1100 mile '67 Camaro battery clamp and bolt. The threaded portion of the bolt is 1" long.
The washer under the bolt head is not flat but instead is conical and the clamp itself is not flat where the bolt goes through.

I'll say that clamp and washer were crushed by an overzealous mechanic. I've never seen a clamp stamped concave at the hole. If I did not feel like tightening that with a ratchet, I could make quick work with a 3/8" or 1/2" impact with an extension and easily crush the clamp and washer without stripping the pierce nut. Service mechanics grab air tools whenever they can, time is of the essence.

Especially if it is a warrany job!

I think you guys are right. I didn't notice that previously. It's just been sitting around on a shelf and I hadn't looked it over well enough.
