This is an excellent brass-plated steel utility hook. Not only is it robust, but at over 3/16" (5mm) in diameter, it has a well-formed ball tip just shy of 3/8" in (9.5mm) diameter.

With an overall height of 2 3/4" (70mm) it projects 1 3/4" (45mm) and mounts with two #6 round-head screws (not included).
