I have one of those micro sets you can buy on Amazon, it has a 2.5 mm socket (just over 3/32") I actually used that socket to fix some frameless glasses.
Is that sockets or nut drivers ?
The kit was sitting in my desk at work, I didn't remember. I looked at it today. I guess it's not a socket per se, as it's driven by the standard 1/8 hex.
I figured that was likely the case.
Those tiny nut driver bits do look handy, if I had a need for them.
