M12 x 400mm Coach Screw DIN 571 | 4.8 Steel BZP

A useful option for commercial signage posts, this M12 x 400mm coach screw provides a hex head fixing with 19mm across flats and a tapered point that helps start the screw into prepared timber. This makes the fixing a strong match for installers searching for a dependable M12 coach screw.

The bright zinc plated 4.8 steel construction gives practical surface protection for workshops, production areas and internal joinery where stainless steel is not required. 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

  • Marine-adjacent timber assemblies where the right grade is selected
  • Boardwalks, pontoons and external timber fixtures
  • Dry indoor timber fixing and general workshop construction
  • Stainless fixings for damp joinery environments
