S-97498A171 M12 x 40 mm DIN 571 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding environments
• Maximum torque transmission via the external hex head design, allowing for secure installation with standard tools
• Exceptional pull-out resistance in wood applications due to the partially threaded and thread-forming design
• Reliable fastening strength with M12 x 5mm metric thread size, ideal for heavy-duty wood connections
• Easy alignment and penetration provided by the pointed tip, reducing installation effort and preventing wood splitting
• Consistent dimensional accuracy meeting DIN 571 specifications, ensuring interchangeability and predictable performance
• Environmentally compliant manufacturing, adhering to RoHS 3 and REACH regulations for safe and sustainable use

Professional Applications & Engineering Value

Engineered for heavy-duty wood fastening, these M12 zinc-plated steel screws address common challenges in construction and carpentry. The thread-forming tapping method creates strong, permanent threads in wood without pre-drilling in many cases, minimizing labor and material stress. The partially threaded shank concentrates grip at the engagement point, significantly enhancing pull-out resistance—critical for structural applications like timber framing, decking, and furniture assembly. The external hex drive and robust 19mm head width allow high torque application, preventing cam-out and ensuring tight, reliable joints. This combination of metric precision, durable zinc plating, and optimized thread design delivers consistent performance, reducing failure risks and maintenance needs in professional woodworking projects.

Specification Summary & Compliance

This screw features an M12 thread size with 5mm pitch and a minimum thread length of 24mm, ensuring secure engagement. It complies with DIN 571 standards for dimensional accuracy and mechanical properties. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting strict environmental and safety regulations. The right-hand thread direction and 40mm overall length provide versatility for various wood thicknesses, while the zinc-plated steel material offers reliable corrosion protection in indoor and protected outdoor applications.
