Carbon Steel Wood Screws
Product Overview
This product is a hex flange head mechanically galvanized wood screw, which is a high-performance fastener designed specifically for timber structure connections. Using medium carbon steel as the substrate reinforced through heat treatment, the product adopts a Class 3 mechanical galvanizing process for surface protection, combining high strength, high corrosion resistance, and convenient construction. Its hex flange head design, sharp cutting thread, and resistance-reducing reduced shank allow it to adapt to various woods and outdoor scenarios, making it an ideal connector for log cabin construction, outdoor platforms, garden landscapes, and other engineering projects.
Product Applications
Construction of outdoor preservative wood platforms, boardwalks, fences, and pavilions.
Node connections for lightweight log cabins and garden landscape wood structures.
Fixed installation of outdoor flower stands, patio furniture, and landscape sketches.
Humid, semi-outdoor timber structure scenarios require high corrosion resistance.
Product Features
High Corrosion Protection: The Class 3 mechanical galvanizing treatment delivers a uniform coating free of hydrogen embrittlement. Its salt spray performance far exceeds regular zinc plating, making it suitable for outdoor humid environments.
Efficient and Stable: The hex flange head is integrally formed and features a built-in washer to prevent loosening and slipping. It accommodates socket tools, ensuring large-torque installation without cam-out.
Construction-Friendly: The sharp cutting thread + reduced shank design eliminates the need for pre-drilling and resists splitting wood, making it adaptable to a wide variety of timbers.
