What is it? And why don't you have one?
This comes in very handy in my line of work....
I'll check back later and see if anyone got the answer.
Beats me...maybe a guide of some sort for alignment of machinery bolts/parts for layout.
Looks like it would make a great ninja weapon.
It's a micrometer.

It's designed for marking the centers of round stock, but I'll bet it would be good for marking the centers of bolts, by intersecting two center scribes at roughly ninety degrees.

Made of hardened steel it should last a career or two.
It will find the center of any shape, including my favorite massive bolts.
That's the smallest my foot has looked in decades...
In the second pic you can see the remains of a previous surveyors work in finding the center of the bolt. Think his location will meet tolerance?

Prolly a good 1/8"-3/16" difference there!

I'm embarrassed to say I've never seen one before. I usually made a template with a flat washer and string, then a dot with the sharpie, much faster than measuring and hatching each one.
