If you are using the Sheldon Brown method, you would turn the wrench clockwise,

A large socket wrench will not fit into the cup, so you will need some small diameter washers to space the head ofthe bolt out so that the socket wrench can reach it. This is what I use the four split lockwashers for. I didn't need lock-washers as such, but the readily available flat washers were too large in outside diameter to fit into the cup.

To remove a right threaded fixed cup (French or Italian), tighten the bolt with the socket wrench from the inside of the bottom bracket, holding the nut with the box wrench. Once the bolt is as tight as can be, keep on tightening it, until the cup screws itself out. Once the cup starts to move, turn both wrenches together.
