This is a special phillips flat DIN965 machine screw measuring M3 X 0.5 X 9MM and manufactured in the USA using steel with zinc plating finish.  These parts we typically supply to our customer with a production run for each order at the quantity requested, typically around 3,000 pieces.  While a variety of M3 X 0.5 DIN965 screws are available as standards, the 9MM length is often an impossible item to find off the shelf and requires production as a special.
