I was recently pressed into service to hang up some curtain rods. The hardware came with some funny screws that I've never seen before. They looked pretty much like normal #6 pan-head wood (sheet metal?) screws except that the diameter of the head was significantly smaller than on a normal #6 pan-head.
This seems like a trivial point except that I needed to get longer screws and the way the stupid thing was designed, a normal head was too big to fit where it had to fit. After much time wasted searching the fastener isle at the borg, head scratching (and not a small amount of colorful language), I ended up taking some stock screws and grinding the heads down to fit.
So, my question is, is there a standard name for this "smaller diameter than a normal pan-head" screw?
