Yes, I saw them on ebay yesterday but was not 100% sure what to do. Good to know that you are here, and good to know where they come from! I will order 6 from you to compare and try!
Actually it's interesting that you said the originals would have had bigger heads with 0.25" (6.25 mm) instead of 0.219" (5.56 mm). Because the 0.219" seems to be what I have (actually they are like 0.21" and not 0.219" in my case) and where I think those might have been the original screws.
0.25" seems to big to me, but you also show HB-2 bass humbuckers on ebay, so maybe they used that bigger head?
Do you say screw 1 is the new one you had custom made and 2 is the original one? Because screw 2 with that slightly domed head does not look original to me!
It's a confusing topic, so I am looking forward to GADs investigation! In any way, your screws might be a good solution for me and I will later compare to the screws GAD ordered.
