M6 x 50mm Coach Screw DIN 571 | 4.8 Steel Galvanised

Where equipment mounting onto timber needs a strong timber fixing, this M6 x 50mm coach screw offers a 30mm threaded section, 6mm shank diameter and 4.8 Steel Galvanised construction for dependable holding power. It is particularly useful for outdoor timber construction and exposed fixing work where a 4.8 steel galvanised coach screw needs a clear measurable specification.

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 DIN 571 form gives a familiar coach screw profile for specifiers replacing like-for-like fasteners in existing timber assemblies. The 6mm diameter gives a balanced option for everyday joinery, fencing and support frame installation.

Common Applications

  • Roofing battens, bearers and heavy timber fixings
  • Joinery projects requiring a hex head wood screw
