Arca Swiss p0 rotator lock: Need to know type of screw

Hi,

I need the exact type of screw that will fit into the hole and replace the original.

To clarify: I'm not looking for a "replacement", as I do have the original lock, but a simple screw that will fit in its place. It can be a hex, a phillips or just about any type as long as the diameter and threading are a 100% match. It doesn't have to be the exact length but it should be pretty close (it can be a little longer).

I have a whole bunch of screws laying around but I couldn't find anything that would fit properly. So, basically, I need someone to post a link on ebay. OR to tell me the exact type of screw and I'll go look for it.

Thanks!

Take the original to Lowes or Home Despot. They have thread checkers in the hardware departments & will be able to match most threads..

I'll bet money its a metric & they will probably have several variations with the correct thread.
