Review on 📺 Mount-It! Height Adjustable TV Wall Mount Bracket - Gas Spring Arm with Full Motion Articulating Design, Suitable for Flat Screens up to VESA 400x400 mm and 44 Lbs - Silver by Bob Ramthun

I need a mount that allows vertical movement and that works great. To make assembly easier, I suggest you buy other hex bolts with the specs posted in another review, drill holes, then use hex bolts to get a snug fit, then take them out and use screws. assuming they have a Phillips head. If you only use the included Phillips head screws, you may tear them off during installation and you won't be able to fully insert (or remove them if you ever have to). However, you will need to use a Phillips head for final installation to be able to cover them with nice caps that give a polished look.
