The Honda 90351-SB2-003 Flange Nut (8MM) is a genuine OEM Flange Nut (8MM) designed for HS520 and HS720 single-stage snow blowers. As a direct Honda OEM component, this nut is produced to the same specification as the original hardware installed at the factory. It is listed for both the HS520 and HS720 — always verify your unit's serial number against the fitment table to confirm this is the correct part for your machine before ordering.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this flange nut matches the original specification for HS520 and HS720 single-stage snow blowers, ensuring a correct, consistent fit.
- Integrated Flange Design — the built-in flange distributes clamping load across a wider bearing surface than a standard nut, helping fastened components stay securely seated through vibration and seasonal use.
- Serial Number Verification Advised — Honda updates hardware specifications at production breaks, so confirm your snow blower's serial number against the fitment table to ensure part number 90351-SB2-003 is the right match for your unit.
A flange nut is a standard fastener with a wide, integral collar on one end that acts as a built-in washer. In a single-stage snow blower like the HS520 and HS720, flange nuts are used throughout the machine to secure components against the continuous vibration generated during operation. The flange spreads clamping force over a larger surface area, reducing the chance of fastener loosening over time. Using the correct OEM replacement ensures thread compatibility and maintains the proper clamping torque that Honda engineered into the original assembly.
