Adjusting the static pad with the OEM M8 screw will not help prevent the pads wearing as they have. The tip of the socket set screw is the only place the back of the static pad is in contact with, so that is not a flat, stable, large perpendicular surface.
One positive thing that was mentioned before is to emulate some race set-ups:
"the static side would not have an adjuster fitted, just large shims of various thickness that fitted snugly"
However, better still (especially if in conjunction with the above) is to pack the slave cylinder in tight beneath the circlip so the chance for uneven pad wear is no longer the result of the actuator flopping about in it's housing. Shims, thick washers filed to fit will do the job & as far as the slave side, the job will only need doing once.....
