Key Features
- Genuine OEM Part — sourced directly from Honda, ensuring the bolt meets the original design intent for HR215 and HRC216 lawn mowers.
- Correct 8MM Sizing — the (8MM) designation identifies the specific variant; verify it matches your application before purchase.
- Direct Replacement — replaces the original bolt on a one-for-one basis, with no reworking or adaptation needed during installation.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your mower's serial number with the fitment table to confirm this is the right bolt for your machine.
A sealing bolt is a threaded fastener designed to close off a port or passage within the mower, preventing fluid leakage and maintaining the integrity of the system it serves. When a sealing bolt loosens, becomes damaged, or is lost, the sealed passage it covers can allow oil or other fluids to escape, leading to low fluid levels and potential damage to the mower over time. Using the correct OEM bolt, with the right thread size and sealing properties, ensures the passage remains properly closed during operation.
