The MACSIM 10G-10x100mm Countersunk Treated Pine Screw is specifically engineered for use with chemically treated timber, providing reliable fastening performance in outdoor decking, landscaping, and construction applications. Featuring a galvanised coating that resists corrosion from both weather exposure and the chemicals used in treated pine, these screws deliver long-lasting durability in demanding outdoor environments.
Each pack contains 50 screws with a 10-gauge diameter, 10 threads per inch, and 100mm length, making them ideal for securing treated pine decking boards, framing, pergolas, and retaining wall structures. The countersunk head design sits flush with the timber surface for a clean finish, while the Phillips drive allows for easy installation with standard power tools. The coarse thread pattern provides superior grip in treated softwood, ensuring secure, permanent joints that withstand the test of time.
