@Freakbro I think I see.
So you have that outer section with 4 threaded studs that are a fixed part of it?
You then have a glass screen which is I'm guessing held in place by a metal plate fastened to the studs with small nuts?
Yep. I've rang Esse on the off chance those studs were a serviceable part (if one sheared) but they didn't ring me back, going to chase them up but I don't think they are.
