These fasteners feature a drill-bit point that cuts its own hole as it is driven in, eliminating the need to pre-drill a pilot hole. Tradespeople use them extensively for attaching sheet metal, HVAC ductwork, and steel framing. The nickname simply clips the word self-tapping into a faster, casual shop term.
