A:Answer Thank you for your inquiry! For the stand legs of your Insignia NS-75F501NA25 TV, you need M6 screws, about 27mm long. You can buy these at most local hardware stores. Just ask for M6 screws that are around 27 millimeters in length. You might also find them online at places like Amazon. If you have any other questions or need further assistance, feel free to ask! - Mae | Insignia Support
