Sourced directly from Honda, this bolt matches the original specification for the HR21, ensuring a proper fit without modification. Confirm your unit's serial number against the fitment table before ordering to make sure part number 90105-952-003 is the correct bolt for your machine.
Key Features
- Genuine Honda OEM — an authentic Honda part, identical to what was installed at the factory on the HR21 lawn mower
- Correct 8MM Sizing — the 8MM hex bolt dimension ensures proper thread engagement and clamping on the HR21
- Serial Number Verification — Honda updates hardware specifications at serial breaks, so check your HR21's serial number against the fitment table to confirm this is the right bolt for your unit
An 8MM hexagon bolt is a standard threaded fastener used to secure components on the HR21 lawn mower. While simple in form, using the correct OEM bolt ensures the right thread pitch, shank length, and head geometry for the application — variables that matter when a connection needs to hold under the vibration and load a mower generates during regular use. Installing an incorrect bolt can result in under-clamping or thread damage, leading to loosened components over time.
