The drum retaining screws I have are not long enough to screw into the hub of my Ruby,they are 1/2” and I need
9/16”.
I intended to look for some at the NEC but when offering the screws up ( without the hub) they do not grip cleanly. The question is what thread and size should they be as I do not want to force in a screw of the wrong thread.they appear to be a BA “0” thread.
If this thread is correct then I can use a tap to clean them up
Replies would be appreciated.
