Does anyone know if the H9 Pro Link threads are actually 4-40 or might they be 3mm? These look VERY similar to Lunsford Turnbuckles used in the RC Car World, and the Lunsfords are threaded 3mm (per Lunsford's web.site). I know Horizon states that the H9s are 4-40, but I just wanted to confirm if this is correct before purchasing them. (Tower mis-states that the Lunsfords are 4-40).

Thanks in advance!
