Timco Stainless Steel Decking Screw

This variant of the Timco Stainless Steel Decking Screw is supplied as a pack of 250 screws in a 4.5mm diameter, 65mm length — well suited to thicker decking boards or applications requiring additional fixing depth and pull-out resistance. Manufactured from A2-304 Austenitic Stainless Steel, these screws are engineered for demanding outdoor timber construction environments, including those exposed to moisture, weathering, and corrosive species such as oak and cedar. The double countersunk head with ribs delivers a neat, professional countersink while reducing the risk of head shear. The helix shank efficiently clears debris during driving to reduce friction and improve clamping force, and the single slash point limits driving torque to help prevent timber splitting — particularly valuable when working near board edges. Each trade tub includes a PZ2 S2 driver bit, ready for immediate use.
