Tap/drill sizes.  And I'll venture a guess its not a vernier but a Dial/Digital caliper

 

Also not sure why state metric tap sizes: just subtract the pitch from the proper diameter.

SAE, is witch craft with no formula.

Right. Digital. I guessed as much it was some such thing. Wondering if it was some sorta standard size for nuts/bolts and if so what.

[G+_Paul Zak]

Common screw pitches and drill sizes.

Is anyone other than old Jag owners (owners of old Jags!) interested in Whitworth?

[G+_Eddie Foy]

widthorth is S.A.E pitchsizes.  Nothng magical, archaric or odd.  BTS would be.

Sure does. Exactly what I was asking. Thanks.

A 1/4-20 is not  SAE?  lol

This reminds me of a semantics problem with our nut-n-bolt bin troll. Sure, head size != thread size, but when you know exactly what I'm asking for, why play games with those you're there to assist? I told him if he didn't give me what I needed to fix the equipment I'd enter his cage and give him the beatdown he knew he deserved. He tried to file a grievance through the union, and they told him to quit causing trouble and do his damn job. He retired later that year.

 

Still don't know why I have a Reed & Prince driver mixed in with my set...
