RC10 ball studs

[Nmore14]

Hello everyone and happy Father’s Day . Quick question hope you can help me out . Looking for a ball stud that is just a little longer than the ball studs that come with the rc10 40th kit . The servo arm is a little thicker that I’m using and I want to use a nut on the back and the stud length isn’t long enough. Is the ball studs measurement from the threads only ? Or the whole thing .
Any help would be great

Typically, the listed length is the thread length.

There are also standard, low profile, tall, and standoff styles. This refers to the ball side.

While not common in the 4.3mm (RC10 size) size, there are also internal threaded ball studs.
