The Honda 90011-952-000 Flange Bolt (8X100) is a genuine OEM fastener designed for HR21 and HRA21 lawn mowers. As a direct Honda OEM component, it is manufactured to the same specifications as the original hardware, ensuring correct thread engagement and clamping load. Honda supersedes parts at serial breaks, so confirm your mower's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt matches the original thread pitch, shank length, and flange diameter specified for HR21 and HRA21 mowers.
- Exact Dimensional Fit — the 8X100 specification ensures the correct thread size and length for a proper, secure installation without modification.
- Mower-Specific Application — listed for HR21 and HRA21 lawn mowers; verify your serial number against the fitment table to confirm this is the correct bolt for your unit.
A flange bolt combines a standard bolt with an integrated flanged washer beneath the head, distributing clamping force across a wider bearing surface. This design helps maintain consistent clamping load at the fastened joint and reduces the risk of loosening under the vibration typical of lawn mower operation. Using the correct OEM-specified bolt ensures the joint performs as Honda intended; an incorrect thread pitch or shank length can compromise clamping integrity or prevent proper assembly.
