Timco Stainless Steel Decking Screw – 50TDECKSS

This variant of the Timco Stainless Steel Decking Screw is supplied as a pack of 250 screws in a 4.5mm diameter, 50mm length — a popular choice for standard-thickness decking boards where a reliable, flush finish is required. Manufactured from A2-304 Austenitic Stainless Steel, these screws are built to withstand the demands of outdoor timber construction including exposure to moisture, weathering, and corrosive species such as oak and cedar. The double countersunk head with ribs ensures smooth countersinking and reduces the risk of head shear, while the helix shank clears debris to improve clamping performance. The single slash point cuts cleanly into timber, minimising splitting even when fixing close to board edges. Each trade tub includes a PZ2 S2 driver bit for convenience on site.
