A:Answer Hi Insignia Customer. Thank you for raising this concern to us. For the TV model: NS-39DR510NA17, you will need to have M4 size 16 mm length screws. However, we don't have any reference regarding the screws needed for the TV model: UN55JU6700FXZA. You may need to contact Samsung to identify the specific screws needed. The other option is to just purchase a TV Wall mount hardware kit (model: NS-HTBOLT1). Since both the Televisions are VESA compliant, this kit should have all types of screws needed for TV wall mounting and you just have to test each to identify what's compatible. I hope this helps. Please let us know if you need further assistance. Have a nice day! - James | Insignia Support |
