- Pan head screws manufacturers
Why should you use BS EN 4073 - Pan head screws?
Pan head screws are a common head type of non-countersunk screw head used in wood screws, self-tapping screws, self-drilling screws, and machine screws. They have wide heads, a flat bearing surface, high vertical, chamfered, or curved sides, and a flat or slightly domed top surface with a recessed socket.
Cadmium Electroplating (Nadcap Accredited) Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacrificial coating," corroding before the substrate material.
BS EN 4073 specifies the characteristics of pan head screws with a six lobe recess and coarse tolerance shank in cadmium plated alloy steel. This can benefit you as this information is used in various aerospace applications. This can help you increase safety in operations.
