What size is it?

What size is the left handed screw that is used on th e1/2 inch drive transmission. I need to order 2 and do not want to order the wrong size. Thanks in advance.

left hand, metric #6

And, if I’m not mistaken, its countersunk. I don’t know the angle (or if this size screw even has more than one type of countersink)
