Swing Arm Grease Nipple

Anyone happen to know what size thread this thing is off hand? Apparently Kawasaki decided nobody needed new ones ever and my crappy grease gun/adverse conditions has ruined mine. It looks to be the same part for the Z1/900/1000/650/750 engines (and maybe H1/H2/etc).

I got mine a Sears Hardware. Metric and Std selection. Found the size using a tap and die set, cant rem the size....mine is aftermarket anyway.

That's what I was expecting, just not sure of the size, guess I'll size it out.
