How are self drilling screws measured?
They are measured from the top of the head to the tip. Hex and hex washer head screws and bolts, 
although flat on the top and the bottom, are measured from the bottom of the head. From that point 
to the tip is the length of the screw. Self drilling screws are measured all the way to the end of the 
drill point tip.
Do you need a pilot hole for self drilling screws?
While self-tapping screws will tap a hole into a soft material, self-drilling screws are capable of drilling 
a hole into anything from metal to wood. This key difference is self-drilling screws have a tip like a 
drill bit, so they do not need a pilot hole.
