A2 type stainless steel decking screws, durable and resistant to outdoor conditions. These countersunk head screws with rifled shank are driven using TORX bits, which ensure maximum grip and block twisting. The partial thread with rifled shank in the middle ensures fast bite and forms a gap between the screw and board, which prevents screw head removal as the board expands or shrinks. The screw features underhead milled ribbing that enable perfect screw rotation and screwing close to edges with no crack formation. Suitable for various types of wood.
