I've seen socket cap screws the other way 'round - metric threads with
fractional hex sockets. If you order a Huco Oldham coupling (made in
Engalnd) with a fractional inch bore it comes with them. Order a
metric bore and you get regular all metric screws.

Interesting.

I had no idea the practice might be so common.

Thanks, All.
