The limit screws do not control the derailleur on the sprockets between the two extremes. These are set using the barrel adjuster and tension on the inner wire.

What does H screw do?

The H screw dictates how far towards the frame the derailleur can move (the higher limit). Turning it clockwise moves the jockey wheel closer to the spokes, counter clockwise, closer to the frame. You want the uppermost jockey wheel to sit directly below the smallest of the sprockets.

What does the B screw do?

The B-gap or B-tension screw is located at the very back of your derailleur. It pushes against a tab on your frame’s derailleur hanger, allowing you to adjust the distance between your rear derailleur’s top pulley and the cassette.
