Even when the screws appear identical, one has a flat point at the side of the tip, and the tip itself may be a tad shorter; that is the front screw. If another screw is put in its place, the crane may bind and the cylinder will be hard to open.

I removed both screws again. For the ever-lovin' life of me they look exactly the same and neither one of them has a flat point near the tip. I reversed them. There seems to be no change in look or function. I give up.
