I searchbar'd and similar questions have been asked before but none asking specifically what i need to know.

Do the schaller strap locks and dunlop strap locks have the same sized screw?

I think so though just use your stock screw that came with the guitar as they won't go loose like i've found the Schaller ones have.

Well I don't have my original screws. I have schallers installed but the god damn nut on the strap clips always falls off and so one got lost and you can't find a replacement for them unless you reorder the entire strap lock set,
But my friend is offering me a set of dunlops for 10 dollars so i have nothing against buying them as long as the screws dont slip out of the guitar.
