the high quality dropout adjusters are slotted at the after end (under the knurled brass cap) for a jeweler's screwdriver.. this is the best way to adjust them

>>"Justin- Have you not seen drop out adjusting screws with the knurled or wing form on them?"
Yes, and the knurled form often unscrews when turned to the left. This is what prompts me to ask why they thread them this way. that PV adapter on the valve, go missing."
This strikes me as another reason to put the knurled/cap nuts on the axle side. If they are butted up against the axle they can't go anywhere. "One of my anilities is to tighten the cap really well when I work on a bike with them."
I would say your precaution is reasonable. But I still don't understand why the screws are threaded from front-to-rear.
