[Parts useful for machine setting and performance improvement] This is a set of countersunk screws with flat heads. If you countersink the holes in plates attached to the underside of the chassis, the screw heads will not protrude, resulting in a smooth bottom surface, preventing the screws from contacting the track surface. The black color also makes the screw heads less noticeable. Be sure to countersink the holes in the plates you are attaching using a 2mm countersink bit.
