What tool should I use to unscrew a hard-to-access hexagonal screw

screws

I recently bought a place which came with the appliances, one of them being a dishwasher. I'd like to extract the dishwasher from its compartment.

From what it seems, the only thing preventing me to do that is a pair of screws legs that lift-up the dishwasher. Those screw legs have a hexagonal head but the area to access them is very narrow.

Here is a picture (of the side which has the more room. I couldn't even take a picture of the other side as there is no way to have direct visibility over the screw head):

The screw is really small. I'd say the head's diameter is about 4 mm. I suppose, I'd a need a tool with a head like that:

But the only one I have is shaped like a screwdriver and is too tall to fit in the available space.

I tried to look online on various sites (Home Depot and alike) but I don't even know which tool I'm looking for, let alone the name for it.

What tool can I use for that job ?

Those are levelling legs.

Dishwashers are either held in via screws on top of the dishwasher that attach to countertop above, or that screw the side (look roughly 1/3rd down just inside the DW door) of the dishwasher to the surrounding cabinet.
