This fastener, installed on the sliding surface of the aluminum alloy window frame, can reduce the vibration of the window sash caused by wind and reduce the noise generated by the vibration. A screw hole is drilled on the outer side of the sliding surface of the window frame. One or two screw caps are welded onto a rectangular iron block. The iron block is fixed to the sliding surface with screws. A screw is inserted into the screw hole of the iron block. Rotating the screw stabilizes the window sash. When the window sash is pushed or pulled, the screw is loosened. One or more pieces of ordinary plastic packaging tape are inserted on both sides of the plastic block on the upper part of the window sash to reduce the gap between the window sash and the upper slide. The simple installation structure can reduce the noise generated by wind blowing the window sash. This invention can also install fasteners on previously installed aluminum alloy windows.
