Could be useful as a metric socket. Math says 15.08125 mm.

I have a couple 19/32s. You never need them, until you do.

They're certainly handy to have around.

I used mine for the first time in many years about a year ago. 12 point nuts on connecting rods. I am thinking it was an early 283?

You dudes and your unusual sized tools NEED to get into the business of carburetor rebuilding!

S.A.E. published standards about 1912, and a number of the carburetor companies cheerfully ignored them

Two that come to mind are Marvel and Schebler (yes Virginia, these were two separate companies before they were married by Borg-Warner).

And yes, Pontiac used Marvels from 1928 through 1932, until they found real carburetors existed.

Marvel deliberately made EVERYTHING non-standard to discourage the aftermarket.

The wrench/socket sizes are bad enough, but where things really get weird are thread sizes. Years ago, I invested over $10k in taps and dies alone, up to 1/2 inch, with maybe 1/2 a dozen larger.

Yesterday, had to dig out my 29/64th socket to remove a check-valve.

That used to be a common size for the 12 point fasteners for the couplings between a frame 5 gas turbine and the reducer gear box. Don't see them that often anymore in this country as the epa made frame 5's dinosaurs...

I had one I used as a 15mm until I started investing in professional tools.

The twelve point might be good for close clearances, but that one is not flank-drive so it's risky to slip or round the fastener. Also looks to be a 1/2 inch drive, which greatens the ability to round off corners.

I have a couple of 19/32 wrenches that are 100+ years old. They fit the stock, 6 point rod bolts on my 1915 Ford Model T. Came in the factory tool kit, among other oddball tools that are specific to the car. Interesting also is the fact that every fastener on that car is fine thread, and every nut has a cotter key going through it to prevent loosening. Oil pan, cowl lamps, everything. I guess the fact that the USA only had a total of about 150 miles of paved road in 1915 was a likely reason for the buttoned down fasteners.
