(1) thread forming screw with special raised head and finish covers. These screws are the shorter of the 2 versions available metric 4.2 / #8 thread x 20mm length, they have a raised head which accepts the black plastic covers by simple pressure fit.
Used primarily for attaching
lower portions of the interior door trim panels, they can however be
used in just about any other universal application as the screws have a
thread forming cutter end and the caps finish off nicely.
