Vaterra aluminum servo arm issues - clamping screw won't tighten down

[2-shot]

I purchased a Vaterra aluminum servo arm for the new Savox servo that's going on my Ascender. The screw that is used to clamp the servo arm is too short, or possibly the threads in the servo arm are partially stripped. It seems like the hole in the servo arm isn't completely threaded, or the screw is too short.
I'm not sure what diameter the screw is, but it's 5mm long. Probably needs to be about 8 to 10mm long. I'm guessing the screw diameter is a M2.5. It's definitely not a 2mm, or a 3mm!! Tried those already....

Has anyone had any issues with the Vaterra aluminum servo arms? Can anyone verify the diameter of the clamping screw for the servo arm?

Thanks!

I have both the vaterra servo horns that have 23T, and 24T, and yup the 23T screw didn't work at all way too short, but the 24T worked out find.

I have the 25T aluminum servo arm. So, it must be a random issue. It almost seems like the part that the clamping screw threads into, is only partially threaded. It should have been completely threaded, or at least, threaded more than what they are!! LOL!!

I don't think the servo arm is going anywhere without the clamping screw, so I'm not gonna worry much about it.

Clamp screw must be 2.5 or 2.6mm then, get a longer one and make sure that it almost pokes out the other side of the threaded hole for more thread engagament.
