Key Features

A Self-Drilling Screw is a Self-Tapping Screw with the added feature of a drill point. The drill point looks a lot like the point of a drill to cut through sheet metal or steel which eliminates the need for drilling a pilot hole. These self-drilling screws are usually designed for use in soft steel or other metals. Self-drilling screw points are numbered from 1 through 5, the larger the number, the thicker metal it can go through without a pilot hole. A Tek#5 point can drill a 0.5 in (13 mm) of steel plate, for example.It will drill a hole and form the mating threads in one operation.

When tracking mouse movement, you usually need to know the actual position of the mouse pointer. The event object that is passed to the handler contains some information about the mouse coordinates.
