Size Of Ez Servos Thread?

How embarrassing. blush Been there, done that. Are you needing one for the new HD servos? The old EZ Servs used screws that fit Futaba Servos. This may or may not help:

I personally tested the above screw in a Futaba S3010 and it fits perfectly. Seems to be a very popular size for nylon gear servos. Our product #NG2608 Rich

. Futaba servo Horn Screw Standard Machined Screw for S9152, 9155 & S9550

Also found this about the HDD servos from a year ago. Again, may not help:

Futaba 3f (25 teeth) for driving spline/shaft
6.2mm spline (including teeth)

If I was a betting man I'd say this one:

. Futaba servo S3150 Horn Screw 
Diameter: 3.00mm (0.12") Length: 6.00 mm (0.23")

Thanks Dave these are the micro servos from the store with metal gears. No nylon.
