Morning

Not 100% sure regarding a three speed box, but think it is 9/16” BSC (20 tpi) and fairly thin maybe 1/4” or 5/16”.

Both UNF and cycle thread have 1/2-20 threads, but the detail is different. The one here is cycle thread (BSCy), available from https://www.nookysnuts.com/catalogue/fasteners/brightzincplated/nutsandbolts.html , although you might have to thin it down.
