DIN 571 Hexagon Head Wood Screws

DIN 571 hex head wood screws are heavy-duty fasteners designed for wood connections, featuring a hexagonal head for installation using wrenches or socket tools. DIN 571 screws are larger in size than standard wood screws, offering higher load-bearing capacity and stability, making them suitable for high-strength fastening in deck, pier, and large-scale wooden structure projects.
