Alright, machinists and quality control folks.

If you need to check hole sizes or set up comparisons with extreme accuracy, a good pin gage is your best friend.

This is a Vermont Gage pin gage, and you get to choose the exact size you need from .035 inches up to .039 inches.
So, pick your poison: .035, .036, .037, .038, or .039.

It's a single pin, not a set.

It's made from tool steel, which is standard for this kind of precision tool, and it's 2 inches long.

Vermont Gage is a solid, known brand for these things.
It's a plus/minus gage, meaning it's made to a specific tolerance, usually +.0002/-.0000 or something similar—perfect for determining if a hole is within spec.
It's brand new, in its original packaging.

Whether you're setting up a lathe, doing final inspection, or just need a quick check, having the exact size pin on hand is invaluable.

Small, precise, and built to last.

Grab the size you need and get to measuring.
