We've got a fairly decent 16" Victor lathe in the shop (oops, make that
400mm...) with a square indexing tool turret. There is no proper
T-handle wrench for the square head screws to secure tools, I use a 7/16
wrench. Have tried finding one here in AU, but boy, not much of a
selection in real machine shop tools so far. Just burned 20 minutes
trying to find one at MSC in the online catalog, no joy.

Anyone know if MSC carries such? If so, a part number would be great!
Or does anyone have one they could ship to my folks in the next couple
days? Can PP funds from my US account. My folks have a package of stuff
ready to ship to me, so if I can't get one to them within a few days,
will just keep on with what I'm using now. Hell, I'll settle for a 7/16
square socket, I can take it from there.
