M16 x 200mm Coach Screw DIN 571 | 4.8 Steel Galvanised
Built for repeatable timber fastening, this 16mm x 200mm Coach Screw provides a 120mm thread length and 24mm hex head size so the correct socket or spanner can be selected before fitting. It gives specifiers a precise M16 coach screw option for timber projects requiring 4.8 Steel Galvanised.
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. Use a pilot hole suited to the timber density before driving the screw, especially on hardwoods or near board edges. The larger 16mm 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
- Outdoor sleepers, gates and site timber assemblies
- Replacement of corroded coach bolts or wood screws
