A system for mounting a wire screen panel to a frame for screening particulate materials. The frame has a stringer with a ferrule defined therein. The system comprises a screen panel having a first plurality of wires and a second plurality of wires disposed. The screen panel has a first side and a second side disposed opposite from the first side. The screen panel has a first end and a second end disposed opposite from the first end. A plate is disposed along at least a portion of the length of the first side of the screen panel. A fastener having a shaft and a head portion is configured and arranged to extend adjacent to the plate and to engage with a bushing disposed in the ferrule in the stringer. The head portion of the fastener engages with the plate on the side of the plate opposite the stringer such that the screen panel is fixed in position relative to the frame.
