Recommended socket size for threaded connections
The socket must be as short as possible. If the socket is in a recess, then use the maximum
limits for nozzle dimensions (flange connections) in this section.
If the device has antenna extensions, this option extends the maximum socket height. Add the
length of the antenna extensions attached to the device to this value.
