Carbon Steel Wood Screws
Product Overview
This screw is a fastener specially designed for high corrosion resistance requirements and high-strength connections. Featuring a unique double countersunk head design paired with a sharp tail and a standard Phillips recess, this screw can achieve fast, stable, and aesthetic connections in wood, composite boards, and light steel structures. Its core highlight lies in the adaptation of the Class 3 mechanical galvanizing process, making its weather resistance and safety far superior to ordinary electro-galvanized products, making it an ideal choice for outdoor and harsh environments.
Product Applications
Outdoor Wooden Structure Architecture: Due to its excellent corrosion resistance, it is widely applied in the construction of treated wood boardwalks, outdoor pavilions, and log cabins/villas, capable of long-term endurance against outdoor wind and rain.
High-Humidity Environment Decoration: It is suitable for wallboard fixing and furniture assembly in damp environments such as bathrooms, kitchens, and basements, preventing screw rust from staining walls or causing structural loosening.
Industrial and Agricultural Facilities: It is used for fixing greenhouse skeletons, ventilation ducts, metal fences, and other facilities, adapting to complex and volatile industrial or agricultural environments.
Heavy-Duty Furniture and Flooring: It provides strong gripping power and a long service life during the laying of solid wood flooring and the assembly of heavy-duty solid wood furniture.
Product Features
Class 3 Mechanical Galvanizing:
No Hydrogen Embrittlement Risk: It utilizes a physical barrel plating process to avoid the hydrogen absorption phenomenon found in traditional acid picking and electroplating processes, completely eliminating the hidden danger of high-strength screw breakage, making it particularly suitable for high-strength steel substrates.
Ultra-Strong Corrosion Resistance: The coating thickness is uniform and thick (generally meeting or exceeding Class 3 standards), exhibiting excellent rust resistance in neutral salt spray tests, and capable of effectively resisting erosion from rainwater, moisture, and industrial atmospheres.
Double Countersunk Head Design: The head structure is optimized to better sink beneath the installation surface. This not only keeps the connected surface flat and aesthetic but also provides a larger contact area during the tightening process, preventing material crushing.
Sharp Tail Self-Tapping Cutting: The tail is designed with an efficient cutting edge, possessing extremely strong self-drilling and self-tapping capabilities. It can be driven directly in without the need for pre-drilling, significantly improving construction efficiency.
Precision Phillips Recess: The depth and angle of the recess are precisely calculated to bite tightly with the screwdriver bit, delivering high torque transmission efficiency and effectively preventing cam-out and bit slippage.
