The Screw, sometimes called a bolt or fastener, is one of the most common parts found in outdoor power equipment. Some types of screws, like a self-tapping screw or shoulder screw, are very uniquely built for their purpose and must be purchased from the OEM/Manufacturer. Others look identical to the screws you might find in a hardware store. We always suggest purchasing replacement screws from an OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation by the OEM.
