What Is a DIN 571 Hex Head Wood Screw? A Complete Overview

The DIN 571 hex head wood screw is a widely used fastener in construction, woodworking, and outdoor structures. Known for its simple yet robust design, it offers strong holding power in wood and is suitable for heavy-duty applications. Whether you’re building a timber frame or installing outdoor decking, understanding this screw’s design and use can help you choose the right product for your project.

DIN 571 Wood Screw Standard and Basic Dimensions

The DIN 571 wood screw follows the German standard that defines key specifications like head shape, thread form, and dimensions. This screw features a hexagonal head, coarse partial threading, and a pointed tip for direct use in wooden substrates.

Common diameter sizes range from M4 to M16, with lengths from 25 mm up to 300 mm, making it suitable for light to heavy structural connections in timber. Its partially threaded shaft allows for a tight wood-to-wood bond, while the hex head design supports easy installation with hand or power tools.

How DIN 571 Hex Head Wood Screws Differ from Other Screws

Compared to other fasteners like self-tapping screws or machine screws, the hex head wood screw DIN 571 is specifically built for wood. Here’s how it stands out:

• Thread Design: DIN 571 screws have deep, sharp threads that bite into softwood or hardwood, offering excellent pull-out strength.
• Installation: Unlike machine screws, which require a nut or tapped hole, DIN 571 screws are driven directly into pre-drilled holes in wood.
• Head Type: The external hex head allows greater torque to be applied with a wrench or socket, ideal for structural or outdoor use.

Because of these characteristics, DIN 571 screws are commonly used in building timber structures, securing beams, and anchoring heavy components in wood.

Material and Surface Options of DIN 571 Wood Screws

Choosing the right material and finish is critical for long-term performance. DIN 571 hex head wood screws are available in several configurations:

• Carbon Steel: High strength and economical, suitable for general indoor applications.
• Stainless Steel (A2 or A4): Excellent corrosion resistance, ideal for outdoor, coastal, or humid environments.
• Zinc Plated: Provides basic protection against rust, commonly used indoors.
• Hot-Dip Galvanized: Offers thick and durable corrosion protection, especially for outdoor structures like fences, decks, or pergolas.

The choice depends on environmental conditions and load requirements. For outdoor applications, hot-dip galvanized or stainless steel DIN 571 screws are usually recommended.

Thread Design Advantages of DIN 571 Hex Head Wood Screws in Timber Work

One of the reasons why the DIN 571 hex head wood screw is preferred in wood applications is its thread geometry. The deep and wide thread spacing allows the screw to cut into wood without stripping or causing excessive splitting, especially when used with a pilot hole.

The coarse thread ensures high pull-out resistance and strong axial grip. For structural applications where stability and durability are key—such as trusses, timber frames, or heavy wooden fixtures—DIN 571 wood screws deliver excellent performance.
