5/16 is your best bet; no metric choices is closer. [(1/4)(√2)(√3/2)] ≈ 0.306.

You could always turn any 1/4" socket around so that what normally fits over the 1/4" ratchet square is over the nut/bolts head you want to tighten.... then just figure out what needs to go in the other side.

If you have something like 1/4" sockets for Allen, hex, or other 'outies', that would be really easy.

I'm in the minority, but I just pick up a socket that looks about right and try it. If it's too small I try a larger one. If it's too large ...a smaller one. I've had 100% success with this method.

No doubt that works fine if you're somewhere near a source of 12-pt sockets.

A practical solution to the problem.

Socket too small? Use a hammer, it’ll fit.

I like that. You should make a you tube video on cold forging.

Instead of using a 12pt socket, one might drive the 1/4in nut with the 1/4in drive straight off the wrench using a 1/4in female-to-female adapter, perhaps.
