The replacement flat washer here is a part commonly found on many types of small engines, including those in lawn and garden equipment. The washer can be used on various parts of the engine depending on the make and model. The washer can help to spread the pressure of the connection over a wider surface area. This will help reduce damage to the machine at the connection point. The washers are made from metal and there may be a need to replace them. If they have become corroded, bent, or lost, they should be replaced right away. Owners should keep in mind what with some models, the washers will be secured with the use of a push pin. The push pins are sold separately. This is an authentic OEM replacement flat washer that is sold individually. The washer can be used on many types of equipment including lawn mowers, snowblowers, tillers, string trimmers, leaf blowers, edgers, log splitters, and wood chippers.
