Washer-Plain 110-9981

This plain washer is a genuine OEM replacement designed for lawn mowers, zero-turn mowers, and other turf equipment. With a 3/8-inch inner diameter, it’s commonly used as a spacer or load-distribution washer in assemblies such as idler arms, helping maintain proper alignment and reduce wear on fasteners and moving components. Manufactured from durable metal to withstand vibration and heavy use, it’s an ideal replacement when missing or worn washers cause looseness or premature component wear.
