Years ago, when metric fasteners were first being used on a large scale in the U.S., I bought a set of inserts for 6-point socket wrenches that would convert an inch socket to a metric. Never used them so can't say how good they fit. I'll see if I can find them and post a photo.

Here are some photos of the socket wrench inch to metric adapter. An adapter in a 7/8" socket will fit a 20 mm. Others in the set are:
15/16" - 19 mm
3/4" -17 mm
5/8" - 14 mm
9/16" - 13 mm
9/16" - 12 mm (a thicker insert than above)
1/2" - 11 mm
7/16" - 10 mm
3/8" - 9 mm
As you can see they are carried on a ring and have a spring wire tool to retrieve the insert from the socket. I suppose they would work in a 12-point socket and on box end wrenches too.
I don't recall using them, but have them in my travel tool bag now, just in case.

Edit: The adapters fit all the way into the sockets, the photo shows one of the inserts only partially in for illustration purposes.
