You'er Welcome Joe
They do come in nice when you need quick look up.
I think the screw for the Hitachi is a 8mm but I don't have one in my hands so I can't say I'm 100% sure,but it rings a bell.
But I don't think it's 10-32, it will be metric thread for sure the 10-32 is a SAE standard but they look almost the same, a quick way to check is with a 10-32 nut if goes in by 1 or 2 threads and locks up it's metric.
