Milsons decking screws are available in two grades of stainless steel: T304 and T316. They are designed to minimise movement while allowing for the natural expansion and contraction of decking boards. The screws feature a Torx drive head for enhanced grip with the driver bit, and a Type 17 tip for self-drilling into softwood. Flush head decking screws create a smooth, safe, and aesthetically pleasing finish by sitting flush with the deck surface, eliminating the risk of tripping hazards and enhancing the overall look.
