Spanner screws are easily recognizable by the two holes drilled in the top of the head. Sometimes referred to as "snake eye" screws, they are available in stainless steel in Pan, Flat, Flat undercut, and Oval head styles. And now also in metric sizes. They require the matching driver bit to install and remove.
