Description
The text describes a Robertson screw bit, which is a type of fastener used in woodworking. The bit has a square socket and a protrusion on the tool, and a tapered socket. The bit is easy to use one-handed, because the tapered socket tends to retain the screw, even if it is shaken. The bit is also specified as ANSI Type III Square Centre, which means that it is compatible with a variety of screwdrivers.
