The Honda 90481-760-K20 Spring Washer (10MM) is a genuine OEM component designed for H3011 and H3013 riding mowers. As a direct Honda OEM part, it carries the exact dimensions and spring geometry specified for these machines, ensuring the fastener assembly performs as Honda intended. Confirm your mower's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct washer varies by production range.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, so the spring rate, inner diameter, and overall dimensions match the original specification for H3011 and H3013 riding mowers
- Direct-Fit Replacement — replaces the original 10MM spring washer with no modification, fitting the fastener assembly exactly as it left the factory
- Serial Number Awareness — Honda updates part supersessions at serial number breaks, so cross-check your machine's serial number against the fitment table to confirm this is the right washer for your unit
- Fastener Retention — a correctly seated spring washer maintains clamping load and resists loosening from vibration; a worn or flattened washer allows hardware to back off over time
A spring washer is a split or wave-form ring placed beneath a fastener to maintain tension in the joint as the machine operates. As the riding mower vibrates during use, the washer's spring action continuously applies outward pressure against the nut or bolt head, preventing it from backing off. When a spring washer flattens or loses its tension, the fastener can work loose, compromising the integrity of whatever assembly it secures.
