This is a self-tapping screw that can be used on a wide variety of lawn and garden equipment in many applications. A self-tapping screw is used to secure metal, wood, plastic, and brick together. When using a self-tapping screw, there's no need to drill a pilot hole since the screw makes its own hole. The only exception is with metal, which will still need a drilled hole before installation. There are many situations when a screw may need to be replaced. Some screws are damaged or broken, while others can become loose and no longer hold materials together. Screw heads can become stripped, which will also mean they need to be replaced. A visual inspection can often give an indication of whether you should replace a self-tapping screw.
