Hello, Screws are not included with the 39-505 track because the appropriate screw size depends on the window material. For wood windows, four of our 33-078 (#7 x 7/8") flat head sheet metal screws are recommended. For PVC and Metal windows, the length and tread type are determined by the profile, so you would need to match up to what you currently have. by bringing an existing screw to a local hardware store. |
