DIN 571 Hexagon Head Wood Screws

Product Overview

Product Application

DIN 571 Hex Head Wood Screws are heavy-duty fasteners designed for wood-to-wood and wood-to-metal connections.

Featuring a hexagonal head and deep coarse thread, they provide strong holding power and excellent pull-out resistance.

Commonly used in timber construction, fencing, roofing, solar mounting systems, and outdoor structures.

Heavy-Duty Timber Construction: Ideal for fastening structural timber, wooden frames, decking, fencing, and playground equipment.
Use with Wall Plugs: Commonly paired with heavy-duty plastic anchors for securing brackets, awnings, TV mounts, and HVAC supports to concrete or masonry walls.
Pilot Hole Recommended: Pre-drilling helps prevent wood splitting and ensures easier installation. The pilot hole diameter is typically 70–80% of the screw’s outer thread diameter.
Easy High-Torque Installation: The hex head design allows installation with impact drivers, socket wrenches, or spanners for secure fastening and reduced cam-out.

Used for timber construction, fencing, roofing, and wood-to-metal fastening.

Yes, for hardwoods and large sizes. Softwood may not require pre-drilling.

SUS304 for general outdoor use, SUS316 for coastal and high-corrosion environments.

DIN 571 uses a hex head for higher torque and stronger structural load capacity.
