Kelsey Hayes caliper bolts

I hear your points and to be honest I don't have any expectations at this moment other than to put out some feelers and get feedback. While it's unlikely, Maybe things have changed a little in the last 2.5 years. Let's just see what comes back. I don't want to get to far ahead and don't have any real plans other than research at this time.

It's a challenge lol I'm just dumb and naive enough to give it a go. :icon_smi: J/K

In the end our conclusion may be the same but one never knows. If it goes nowhere at least we have some updated info.

I've started a very High level dialogue with a couple of outfits in the NY/NJ area. I've provided basic detail (7/16-20 thread x 13/4" long) ) and sent photos.

I've been asked to get as much detail together about the bolt so they could estimate sample and production costs.

Since I don't have an actual bolt the only information I have is found in the archives of this forum.

What I need to start are dimensions (or the actual Bolts if I find a set for my car).

Specifications:
I basically need every dimension of the Bolt.

A. Hex head thickness top to bottom
I. Hex head width edge to edge (socket size)
B. Shoulder Length from bottom of hex head to the threads
J. Diameter of the Shoulder
C. Length of the threads from the end of the shoulder to the start of the bevel tip
D. Length of the tip from the end of the threads to the tip of the bolt.
E. Diameter of the Tip
F. Full length from head to tip


I can't move forward with out the details. Once I have the bolt specifications details I can continue the discussion and bring up additional points. Please let me know if you stuff to add to the talking points.

* Minimum counts
* Material grade
* Manufacturing Treatments
* Time
* cost

If you have done research previously and want to share that's cool. I'll take any help I can get. Leads, contacts whatever.

Thanks
