Spinning positive posts on RDA?

I purchased a Castle rda yesterday and when I went to put my first build on it the positive post spins when I tighten the screw all the way.

The funny answer would be "don't tighten the screw all the way". The more intelligent answer is, the center post is a "press fit" into the insulator(s)... and your's apparently isn't all that tight of a press fit. It happens.

There are ways to tighten it, but if it's a genuine VapeSmith Castle... I'd just give them a call or e-mail - they'll stand behind it.
