Product Overview
This product is a heavy‑duty timber structure fastening screw compliant with Australian building material standards. It is manufactured from carbon steel with an overall quenching process, integrating a T17 cutting point, twisted shank, and internal hex flared countersunk head in one structure. The surface is treated with mechanical galvanizing Grade 3 for corrosion protection, eliminating the risk of hydrogen embrittlement and providing excellent salt spray resistance. Specifically designed for outdoor preservative‑treated timber and heavy timber construction, it suits Australian garden projects, timber cabins, decks, and other engineering scenarios, balancing installation efficiency, fastening strength, and long‑term outdoor rust protection. It is a mainstream fastener for timber structure engineering.
Product Applications
Outdoor Garden Timber Structures: Installation and fixing of preservative‑treated timber decking, garden fences, trellises, leisure wooden pavilions, and outdoor boardwalks.
Timber Cabin Construction: Light‑frame timber building frames, roof purlins, wall sheathing, and splicing of main and secondary timber beams.
Export Australian Building Material Projects: Compliant with local Australian corrosion protection standards, specifically supplied for export‑matched Australian timber cabins and landscape infrastructure.
Various Solid Timber Substrate Fixing: Splicing and fastening of heavy panels such as preservative‑treated pine, hardwoods, modified solid timber, and multi‑layer plywood, as well as load‑bearing components.
