A fastener device for attaching a rear face of an acoustic to a substrate, comprising an anchor part for attachment to the substrate and a screw part having an inner end rotatably connected to the anchor part. The screw part has a helical member with an outer end capable of penetrating the rear face of the panel when rotated by an elongated drive rod projecting from the outer end. The drive rod is capable of penetrating a panel so as pass fully through the panel when the helical member contacts its rear face, and is accessible for rotation at the front face of the panel to cause the helical member to penetrate and engage a rear portion of the panel, and to secure the panel onto the substrate. The drive rod is removable from the outer end of the screw part after the panel has been secured so that the fastener is essentially concealed within the panel.
