The DIN571 Hexagonal Wood Screw, also known as a hex head wood lag screw, is a high-strength fastening solution designed for secure wood-to-wood or wood-to-metal connections. Manufactured according to the DIN 571 standard, it is widely used in construction, carpentry, furniture assembly, and heavy timber structures where reliable load-bearing performance is required.
DIN571 hexagonal wood screws feature a robust hex head design that allows easy installation with a wrench or socket tool, ensuring high torque application without stripping. The deep, coarse threads are engineered for strong grip in wood materials, providing excellent holding power and long-term stability.
These screws are typically manufactured from high-quality carbon steel or stainless steel (such as SS304 or SS316), offering superior mechanical strength and corrosion resistance for both indoor and outdoor applications.
Standard Compliance: Manufactured according to DIN 571 specifications
Hex Head Design: Enables high torque tightening with standard tools
Deep Coarse Threads: Ensures strong anchoring in wood materials
High Load Capacity: Suitable for structural and heavy-duty applications
Corrosion Resistance Options: Zinc-plated, hot-dip galvanized, or stainless steel finishes available
Durable Construction: Designed for long-term performance in demanding environments
Carbon steel with zinc plating (economical and widely used)
Hot-dip galvanized steel (enhanced outdoor corrosion resistance)
Stainless steel A2 (SS304) and A4 (SS316) for marine and high-humidity environments
DIN571 hexagonal wood screws are widely used in:
Timber frame construction
Wooden roofing structures
Outdoor decking and pergolas
Furniture assembly and wooden fittings
Fence installation and garden structures
Heavy-duty wood-to-metal fastening systems
Compared with traditional wood screws, DIN571 hexagonal wood screws provide significantly higher torque resistance and pull-out strength. Their hex head allows for faster installation and improved control during tightening, making them ideal for professional construction projects.
Each screw is manufactured under strict quality control standards to ensure dimensional accuracy, consistent thread geometry, and reliable mechanical performance. Surface treatments are tested for corrosion resistance to meet international usage requirements.
