Paragraph Number

57

Specifically, the head 210 may have a socket 230 with a non-circular shape that engages a boss (not shown) on a driver with a corresponding male shape. As shown in FIG. 2D, the socket 230 may have a star shape with rounded points. Further, the head 210 may have a threaded socket 232 distal to the socket 230. The threaded socket 232 may receive a corresponding threaded boss (not shown) on a driver. In some embodiments, a driver (not shown) may have the boss and the threaded boss described above, so that the driver can mate with both the socket 230 and the threaded socket 232 for secure engagement with the head 210 of the screw 104, allowing the driver to advance or withdraw the screw 104.
