Information on some mounts being a UNIVERSAL type refers to VESA drilling, which concerns the horizontal and vertical distances between the holes for mounting the bracket. VESA is a worldwide standard for these measurements (HxV). As for screws, there is no diameter or length pattern, each manufacturer is free to define, according to its own criteria, the specifications of the screws.
