more than likely 5/8 and 9/16 wrenches.

I havent used octura couplers in a bunch of years.

1/2 & 9/16 for my octura coupler with the 2 grub screws

Try them until you find two that fit?

Not trying to be a d...Are you ordering wrenches or something or do you have wrenches there?

I knew it was kind of a ridiculous question in the first place but my brother has my wrenches for the next 3 weeks. I didn't want to buy a new set of wrenches just for this. But I don't mind buying just two

I've got those two wrenches with me and forgot that when I ordered the 1521 NEU w/8mm shaft I'd also have quite a bit larger collet. Thank you for your help Alexgar.

I can take the coupler to the hardware store too but I just figured I'd save myself a step and ask here first. Thank you for your help.

Two small adjustable Crescent wrenches will work. I have seen these sell cheap.

Home Depot was selling them for about .99 or 1.99.
