M12 x 140mm Coach Screw DIN 571 | 4.8 Steel Galvanised

This 4.8 steel galvanised coach screw gives fabricators and installers a dependable DIN 571 wood screw with a hexagon head, suitable when garden room construction requires a stronger fixing than a standard woodscrew. This makes the fixing a strong match for installers searching for a dependable 4.8 steel galvanised coach screw.

The galvanised 4.8 steel finish offers a stronger protective layer than standard bright zinc plating, making it a practical choice for fencing, landscaping and external timber frames. The partly threaded body helps pull mating components together, which is useful when clamping brackets, plates or timber sections into position. The larger 12mm shank makes it suitable for heavier timber sections, support posts and bracket assemblies.

Common Applications

  • Construction timberwork requiring a DIN 571 profile
  • Steel plates secured into structural timber
  • Galvanised coach screw fixing for fencing and landscaping
  • Heavy shelving, racking and timber supports
