A:AnswerBoth M6 and M8 VESA Standard Philips pan head screws come in varying lengths. M6 and M* are the metric measurements for the width of the screws (i.e M6 - 6mm and M8 - 8mm) The length is designated as Lxx (xx will be the length in millimeters). The correct width for the screws that will fit into the VESA mounting bolt holes on the LG 65 inch Class 4K Smart UHD TV w/AI ThinQ® (64.5'' Diag), Model # 65UM7300PUA is M6.

Typically, wall mounts will provide you with 2 - 3 sets on screws of varying lengths with spacers to use if necessary...^IFV
