The Honda 90021-KE8-010 Hexagon Bolt (6X16) is a genuine OEM fastener listed for EL5000 and ES6500 generators, the EX5500 generator, and HT3813 and HT4213 lawn tractors. As a Honda OEM part, it is produced to the same specifications as the hardware installed at the factory, ensuring correct thread dimensions and head geometry for each application. Because Honda supersedes hardware across serial ranges, confirm your unit's serial number against the fitment table before ordering to verify this is the correct bolt for your machine.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, with the thread pitch and head size specified for the original application rather than a generic substitute.
- Correct Thread Engagement — the 6 mm diameter and 16 mm length match the original fastener specification, so this bolt seats and torques properly without modification.
- Broad Fitment — listed for EL5000, ES6500, and EX5500 generators as well as HT3813 and HT4213 lawn tractors; check your serial number against the fitment table to confirm applicability.
A hexagon bolt is a standard threaded fastener used throughout Honda equipment to secure components at assembly points. The 6 mm thread diameter and 16 mm shank length define exactly where it is used, and substituting a bolt of incorrect length or pitch can result in under-engagement, stripped threads, or improper clamping. Replacing a damaged or missing fastener with the correct OEM specification bolt restores the assembly to its original condition.
