Carbon Steel Wood Screws
Product Overview
This product is a hex flange head wood screw, which is a highly anti-corrosive, high-strength dedicated fastener crafted for timber structure engineering. The product utilizes a high-strength carbon steel substrate paired with a Class 4 mechanical galvanizing surface treatment, balancing excellent mechanical properties with long-term anti-corrosion capabilities. It can adapt to harsh working conditions such as outdoor humidity and high salt spray. Widely applied in preservative wood engineering, log cabin construction, landscape boardwalks, outdoor platforms, and other scenarios, it serves as a reliable choice for outdoor timber structure connections.
Product Applications
Outdoor Wood Structures: Preservative wood boardwalks, platforms, log cabin framing, pavilions, and fences.
Garden Landscapes: Wooden bridges, corridor frames, outdoor tables and chairs, and landscape wood sketches.
Home Renovation & Construction: Wood joist installation and heavy wood component connections.
Special Working Conditions: Timber structure engineering in coastal high salt spray and high-humidity environments.
Product Features
High Corrosion and Weather Resistance: The Class 4 mechanical galvanizing process provides a dense and uniform coating with zero risk of hydrogen embrittlement. It resists moisture and salt spray erosion, drastically extending outdoor service life.
Efficient and Firm Installation: The hex flange head accommodates standard sockets, withstanding high torque without slipping; the flange surface distributes pressure to prevent wood splitting and provides an auxiliary anti-loosening effect.
Strong Adaptability to Wood Structures: The partial thread + self-tapping sharp point design allows direct tapping without pre-drilling, adapting smoothly to softwoods, hardwoods, preservative wood, and other timbers without jamming.
High Strength and High Reliability: High-strength carbon steel substrate offers excellent tensile and shear performance, making it resistant to deformation or breaking under long-term loads to satisfy engineering safety requirements.
