A:Answer Hi Danny. The metric width of the Philips pan head machine screws that will fit into the VESA Mount bolt holes on the LG UHD 85 Series 65 inch Class 4K Smart UHD TV with AI ThinQ® (64.5'' Diag), Model # 65UN8500PUI are M^ (i.e. 6 mm). The length of the screws will depend on the depth of the wall mount you use to mount the TV. If you are purchasing a new VESA Compliant Wall Mount, regardless of type, brand or manufacturer that supports the VESA Wall Mount Interface Pattern supported on the TV (i.e. 300 x 300 mm) it will come with 2~3 sets of screws of varying length with spacers to use. If you are looking to use an existing wall mount, you can either check the installation guide that came with the wall mount, measure the dpeth or contact the wall mount's manufacturer to inquire about what length is appropriate for the wall mount...^IFV
