A self-tapping screw is a fastening device that secures almost anything to metal through the use of a drill to secure the screw in place. This versatile device can be connected through wood and plastic before begin secured to a metal surface.
Be careful using power tools. Put on protective eye wear before you begin to prevent any injury to your sight. Be sure the power switch to the drill is turned to the off position before you plug the tool into the electrical outlet. Always store power tools in a safe place when you are not using them.
Drilling the Pilot Hole
Use your drill and drill bit to create a pilot hole in the item you want to secure to the metal. Use a bit that has a slightly smaller diameter than the tapping screw you are using.
Spinning the Tapping Screw
Spin the tapping screw on the metal surface. It will turn itself through the metal.
Securing the Tapping Screw
Secure the tapping screw to the metal. Turn the screw in a clockwise direction until it is tightly attached. Be careful not to over tighten the screw. Over tightening could cause the screw to break or the metal to become damaged.
