This genuine replacement part is a self-tapping screw. A self-tapping screw is a small screw that taps into place with relative ease. Lawnmowers have many screws that secure a variety of different parts. Whether they hold the housing of the various mechanical components or are used as mounting screws for other various parts, self-tapping screws are essential in holding all the different parts of the mower together. Over time, self-tapping screws that are exposed to the elements can rust and deteriorate. If they become too damaged, they might no longer do their job effectively and will need to be replaced. Luckily replacing these screws is a very simple process. To replace the screws, simply unthread the damaged screws and replace them with the new self-tapping screws. If the screws are stripped or too corroded to be removed, consider prying them out with a screwdriver or using a pair of needlenose pliers to rotate them out of their position.
