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