DIN571 Hex Head Wood Screw
DIN 571 wood screws are hexagon head wood screws designed for secure and reliable fastening in timber and wood structures. The hexagon head provides a convenient external drive for wrench or socket installation, while the sharp, deep wood screw thread is designed to achieve strong engagement with wood and provide a stable connection. Their robust construction makes DIN 571 screws suitable for applications where dependable fastening and easy installation are required.
We supply DIN 571 wood screws in a range of materials, sizes and lengths to meet different application requirements. Stainless steel options provide enhanced corrosion resistance for demanding environments and outdoor use, while carbon steel versions offer a practical solution for general timber fastening. DIN 571 wood screws are commonly used in timber construction, woodworking, furniture assembly, building projects and other applications involving wood-to-wood or wood-to-material fastening.

Application of DIN571 Hex Head Wood Screw:
Timber Construction
DIN 571 wood screws are widely used in timber construction for joining wooden beams, frames, boards and other structural timber components. The hexagon head allows efficient tightening with a wrench or socket, making these screws suitable for applications where a secure and stable connection is required.
Woodworking & Furniture
For woodworking and furniture applications, DIN 571 screws can be used to connect solid wood components, wooden panels, frames and other wood-based parts. Different diameters and lengths allow the screws to be selected according to the thickness and construction of the materials being joined.
Building & Outdoor Projects
DIN 571 wood screws are also suitable for general building, repair and outdoor fastening projects involving timber and wood structures. SS304 wood screw and SS316 wood screw provide improved corrosion resistance for outdoor and humid environments, while coated carbon steel versions offer a practical option for general construction and woodworking applications.
