HELP - POLO digi4 screw size?

Was wondering if any one knows the size of the screw used to hold the servo arm onto the sero? This is for the Multiplex POLO digi4 servo...

The servo came with a short screw and I need one a lil longer to work with my Xrax m18pro servo-saver. Tried a couple the LHS had in stock and nothing seemed to fit...

Thanks for the help...

I used the screw that came with my Xray micro servo saver and haven't had any problems. I do know the screw size is the same as Hitec servos, I believe 2.8mm.

2.3mm I believe. Hitec sells them.

Thanks for the help guys.. After carefully going through my M18pro kit parts, I found a silver screw that was long enough and fit perfect. Wish I found it before going to two LHS's though...

2.3 sound right because 2.0 (to small) and 2.5 (to big) that the LHS had did not fit... I will look around for that Hitec size to have a spare or two...

Looks like it may be 2.2mm... I found these on Tower:
