DIN 571 Hex Head Wood Screws (Coach Screws)

FULLERKREG supplies DIN 571 hexagon head wood screws — also known as coach screws or lag screws — in stainless steel and zinc-plated carbon steel. The coarse wood thread and pointed tip drive directly into timber without pre-tapping, while the hex head allows high-torque installation with a standard wrench or socket. Ideal for heavy-duty timber construction, decking, fencing, and structural wood connections. Select your material below:

About DIN 571 Hex Head Wood Screws

  • Standard: DIN 571 (Germany) — also known as coach screws or lag screws
  • Head: Hexagon head — driven by open-end wrench, ring spanner, or socket
  • Thread: Coarse wood thread with gimlet point — self-tapping into timber, no nut required
  • Size Range: M6 – M20 (material-dependent)
  • Installation: Pre-drill pilot hole recommended for larger sizes to prevent timber splitting
  • Key Advantage: High pull-out strength in timber — ideal for heavy structural wood connections
