What? What exactly is the pitch/sizing on a USS bolt? Google doesn't
really return much for a USS thread chart... UNS? 7/16-18? TSC was formed
in 1938, perhaps you got their last piece of original stock?

I rigged the 5C to ER-40 to the mills table, then found I needed a draw
bolt about 4" long to keep the R8 from rotating in the ER40 collet. So
I saddled up and ran out to TSC, where I found the 7/16 bolts they had
were only grade 5. So I got one and some washers to adjust the length
with, came back and found the bolt was USS while the butt end of the R8
was SAE. So I'll have to round up some 1/2" A2 and put it all back in
the lathe to apply a g76 and make some SAE threads.
I also found I'll need a better way to clamp it to the table, probably
by making a big v-block and a thick steel bar to clamp it into the V.
Some days I swear its not worth gnawing thru the straps to get up and pee
in the mornings. :(
