Window screws are typically used to secure window frames and glass. The size and length of window screws are usually chosen based on the dimensions and shape of the window frame and glass. The screw's diameter and pitch need to match the threaded hole to ensure a secure fastening without loosening. The length of the screw is selected based on the depth of the threaded hole and the thickness of the components being fastened, ensuring that the screw can fully penetrate the window frame and the fastened components.
