Can anybody help with identifying these?
Well, I know what they are and the size. They are M4 X 12mm socket screws that I have rounded over the sockets with. The head is not a countersink, it is much more of a wedge shape. The socket is a size smaller than normal, I think it is 2.5mm but I didn't look at the hex key I picked up.
They are from a record rp2000 chuck.
What do I search for or are they proprietary?
