Coach Screw

Coach Screws are heavy-duty wood screws with a hexagonal head designed for use with wood, masonry plugs, and light steel. They are driven with a wrench or spanner, providing a stronger fixing compared to standard wood screws. Manufactured to ASTM and DIN standards, they are available in a wide range of sizes, grades, and finishes. The deep coarse threads provide excellent grip in timber and other substrates. They are widely used in construction, fencing, carpentry, and heavy timber assemblies.
