I've just purchased one of these servos for my first 1/12th car and along with it a Kimbrough servo saver.

The only problem is the screw provided with the servo is to short to go through the servo saver and then more than a couple of turns into the servo output.

Could someone let me know the correct sizing of the screw/thread so I can try and find another one but just a little longer?

None of the other servo screws I have seem to fit properly and this is not something I think I should just guess lol.
