The RYOBI 89036008022 is an OEM M10 flat washer designed as a direct replacement component for RYOBI outdoor power equipment. Flat washers serve a critical function in mechanical assemblies: they distribute load across a fastened joint, protect mating surfaces from damage, and help maintain proper clamping force over time. This part is sourced as original equipment, meaning it meets the dimensional and material specifications set by the manufacturer. It is a common service part replaced during routine maintenance or repair of lawn mowers and other outdoor power tools where M10 fastener hardware is used.
This washer is intended for use in residential outdoor power equipment serviced by technicians or knowledgeable DIYers working on RYOBI-branded lawn mowers and similar equipment. It is typically installed wherever an M10 fastener requires a flat bearing surface to prevent pull-through or surface marring on softer materials. This part is suited for hardware-level repairs and reassembly work following component removal or replacement on compatible RYOBI equipment.
Designed as an OEM-style replacement flat washer for RYOBI outdoor power equipment requiring M10 metric hardware. Consult your equipment service manual to confirm fitment for your specific model before installation.
Installation is performed by a technician or qualified DIYer during disassembly and reassembly of mechanical components. Power down and disconnect the spark plug or battery before servicing any outdoor power equipment. Use appropriate metric hand tools and follow the torque specifications listed in the equipment service manual for the corresponding M10 fastener. Inspect surrounding hardware for wear or corrosion and replace as needed before reassembly.
