Squier VM Jazz V Help!

[VeganThump]

I cant find the right size allen wrench to adjust the action on the bridge saddles, i think im going crazy. I have tried metric and standard with no success, anybody know what the right size is, im losing my mind.

Mine is metric, but I don't know the size off the top of my head, sorry.

edit: Not much help, but I can tell you that it is the same size as the ones that Ikea give you with their Japanese Blinds curtain track!!
