Any thoughts where I can buy a longer version of this bolt?
My Summit rod stretch gauge has a 1/4-28 by 1 inch socket screw that has a dog leg like appendage on the end to seat in the rod bolt dimple. See picture below.
Any thoughts on what this bolt is called and I where I could buy one that's 1 1/2" inches long?

I would look at McMaster Carr they carry a lot of fastners. I do not know how accurate it needs to be but instead of turning the end of the bolt down, could you drill a hole in the end of a bolt and use a dowel pin as the nipple???

Can you show a picture of the end with the pin in it ? You might be able to pull the pin out and get a longer one instead of getting a longer bolt. I doubt you will find a screw with the pin already in it.
That being said it might be easier to just get a set of longer points for the dial indicator.

I had a problem finding bumper bolts that were long enough when I had my 54. I bought some 1/2 inch allthread and cut a short pience. I put the bolt and the althread in my vise and took my Mig welder and tack welded them together. I don't know if that would work in your application or not.

Thanks Bill, that visual helps a lot. As mentioned, a lathe is the most accurate way to replicate that configuration. If you have a drill motor and a bench grinder, you could chuck a bolt up in a drill and grind a taper point on the end of the bolt. It would look different, but still provide a small contact area and serve the same function as the fancy bolt tip.

FYI - Super tight clearance with the nut and the rod. (bolt bottomed out)
I'll probably remove the nut and just blue loctite the screw into the fixture.
It would have been better if they used a 1 1/2" bolt.

BillK.... Thats a nice unit, easy to handle and rigid.

Now, y'all are brainfvcking it to death. Look at the ARP tool: it's just a point on a bolt. You could do that with a drill and a bench grinder. BUT, some people aren't happy unless they spend a bunch of money and overcomplicate things.
