HS-85MG servo arm screw size?
#1

Hey guys, I've found myself in a situation where due to space limitations and the need to remove the arm while the servo is installed, I need to put a socket head screw in the arm of one of these servos. Now I originally thought they'd be the same M2.6 as the larger servos and have some of those as well as M2.5 and M2.0 stuff here. Needless to say none of it fit....
I measured the thing and I'm wondering if you can confirm the screw size, is it a M2.3 x 0.4mm x 6mm? I don't suppose a socket head screw of the appropriate dimensions is available from you, or do I have to hit the online hardware vendors?
Thanks.
