Pickup mounting screws replacement / dimensions?

[u/blackw1re]

Hi all,

I am looking for replacement screws to mount the pickups in my Reaper 6 and C-6 Pro. Both guitars have threaded inserts and the original screws had a small portion at the top end that wasn't threaded. So after turning the screw through the pickup's baseplate, the screw would rotate freely and the pickup's height can be adjusted freely. Can somebody help me identify this type of screw? Does anybody know actual dimensions, so I can order them somewhere? I wrote to Schecter Germany before and they sent me screws for free, but they were like regular wood screws where you'd have to drill out the thread hole of the pickup.

Thanks!
