Confirm fitment using part number 90213-S3Y-000 against the serial number on your machine before ordering.
Key Features
- Genuine Honda OEM Hardware — an authentic Honda fastener built to the same specification as the original, ensuring thread engagement and clamping load are exactly as Honda engineered them.
- Integrated Flange Design — the built-in flange distributes clamping force over a wider bearing surface, eliminating the need for a separate washer and securing the joint the way the original assembly was designed.
- Broad Fitment Across Honda Equipment — listed for GC190 horizontal shaft engines, GCV190 and GSV190 vertical shaft engines, HRB217 and HRX217 lawn mowers, and HS520 and HS720 single-stage snow blowers.
- Verify Your Serial Number — Honda updates fastener specifications at production breaks, so cross-check your machine's serial number against the fitment table to confirm this is the correct nut for your unit.
A flange nut is a standard hex nut with an integrated wide-diameter flange on one face. The flange acts as a built-in washer, spreading the clamping load across a larger surface area and reducing the risk of the fastener pulling through or loosening under vibration. On outdoor power equipment — which is subject to constant engine vibration, seasonal temperature swings, and outdoor exposure — using the correct replacement fastener with the right thread pitch and flange diameter matters. A fastener that does not match the original specification can work loose over time or fail to develop the clamping force the joint requires, leading to component movement or misalignment.
