This is a double horizontal white nylon stayput fastner. They come in packets of 10. We would suggest you use 6 gauge X 3/4 square or pozi drive stainless steel screws although 1/2 inch would be long enough in most cases. Care should be taken on fibre glass surfaces making sure the screw hole is counter sunk otherwise the fibre glass surface will chip off.
