TyPES of HEADS
Note: When ordering slotted bits, please remember that head sizes and slot widths of hardened, self tapping, and sheet metal screws do not conform to the same
specifications as standard wood or machine screws described in the chart below. Also, because of variations in these dimensions among screws from different
manufacturers, bits should be ordered to head and slot size rather than screw size.
