Why Choose the M8 x 75mm SS316 Coach Screw?

When mounting hardware to a deck or timber structure, the depth of your fixing is just as important as the material. This 75mm coach screw provides the industrial-grade "reach" needed to bridge the gap between your hardware and the structural timber below. By utilizing 316-grade steel, you ensure that even the most hidden fasteners remain rust-free and structurally sound for the life of the installation, preventing the "wobble" often associated with inferior fasteners.
