A feature of the design of the DIN 553 screw is the absence of a head, which is replaced by a straight slot in the end of the metalwork. The other end of the fully metric threaded rod has a tapered point, which makes it easier to insert the screw into the metric threaded hole and self-lock when stopped.

DIN 553 screws and pointed end have convenience and ease of installation. They are screwed using a simple household screwdriver or a power tool with a straight bat.
