Abstract

A screw head slot shaper includes a shank and a head slot molding member formed on an upper end of the shank. The shake can be of any shape. The head slot molding member has plural square layers, which respectively have different sizes. So a single screw head slot shaper can manufacture screws with a head formed with a single layer slot, a two-layered slot or a three-layered slot depending on demands. Thus many different tools may conveniently be used for driving screws with a head with a slot of a single or plural square layers.
