Metallics and Avanti Screw, Inc., prime American manufacturers of fastener products, have always worked to present the latest in fastener technology to our distributors and their contractors/users. Hex Washer Head fasteners have historically only offered three drives-the hex, Phillips and the slot. In 1999, we introduced "The QuaDrive" square, hex, slotted and Phillips, in fourteen of the most popular sizes of sheet metal screws.
