Hex Washer Head Tapping Screw

A hex washer head tapping screw cuts its own thread in a pre-drilled hole in sheet metal. The integral washer face under the hex head spreads the load and reduces the chance of pull-through. Drive it with a hex socket or wrench. It is used for sheet metal panels, enclosures and ducting.
