I hope you loctited it. If not it maybe cause some damage.

What do you think a big set screw would do? Like i mean threading the hole and putting in a larger set screw.

Good eye there coolhand. That is indeed a body post screw. The one that I actually used looked just like that but was smaller. And by judging by the amount of force that I had to use to get the thing in there, I don't think I needed any lock tite.:D
