Hex Head Wood Screws
Product Overview
This product is a hexagon flange head mechanically zinc-plated wood screw, designed as a high-performance fastener for timber structure connections. Manufactured from medium-carbon steel substrate, strengthened through heat treatment, and protected with a mechanical zinc plating Class 3 surface finish, it combines high strength, excellent corrosion resistance, and convenient installation. Featuring a hexagon flange head design, self-tapping cutting threads, and a reduced-shank neck structure, it adapts to a wide range of timber types and outdoor scenarios, making it an ideal connection component for wooden house construction, outdoor decking, landscape gardening, and similar projects.
Product Applications
Outdoor preservative-treated timber decks, boardwalks, fences, and pergola construction.
Lightweight wooden houses and landscape timber structure node connections.
Fixing and installation of outdoor trellises, garden furniture, and landscape timber ornaments.
Damp or semi-outdoor timber structure scenarios require high corrosion resistance.
Product Features
High corrosion protection: Mechanical zinc plating Class 3 treatment provides a uniform coating with no hydrogen embrittlement risk, offering significantly superior salt-spray performance compared to ordinary zinc plating, and is well-suited for outdoor damp environments.
Efficient and secure: The one-piece hexagon flange head integrates a built‑in washer function for anti-loosening and anti-slip performance; compatible with standard socket tools, it withstands high-torque installation without stripping.
Installation-friendly: The self-tapping cutting thread + reduced-shank drag-reduction design eliminates the need for pre-drilling, reduces the risk of wood splitting, and adapts smoothly to various timber types.
