Zinc plated coach screws are tough, reliable and easy to use. They have a sharp tip and coarse thread for a firm and secure fit, and a traditional hexagon head allows for greater torque with a socket driver. These single thread screws are ideal for fixing to timber in fencing and joinery applications, and the zinc plating provides enhanced durability. They conform to DIN 571 standards. These coach screws are also suitable for fixing timber to masonry and are popular for satellite dish installations with wall plugs. Zinc coatings prevent oxidation, forming a barrier and acting as a sacrificial anode if damaged.
