The Honda 92101-08028-0A Hexagon Bolt (8X28) is a genuine OEM fastener designed for GX390 horizontal shaft engines, HRX217 lawn mowers, EX3300 and EX4500 generators, and EXW171 welder generators. As a direct Honda OEM replacement, this bolt is manufactured to the exact dimensions Honda specifies, ensuring proper torque retention and a secure fit in the original threaded location. Confirm part number 92101-08028-0A against your machine's parts diagram before ordering, as Honda uses several bolt sizes across its equipment lineup.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt meets the exact thread pitch, shank diameter, and head geometry specified for its application — the same fastener installed at the factory
- Exact Dimensional Match — the 8 mm diameter and 28 mm length are precisely controlled, so the bolt seats fully and clamps correctly without modification
- Broad Honda Fitment — listed for GX390 engines, HRX217 mowers, EX3300 and EX4500 generators, and EXW171 welder generators; verify against your unit's parts diagram to confirm the correct application
- Serial Number Awareness — Honda updates parts at production serial breaks, so cross-check your machine's serial number against the fitment table to ensure this is the right bolt for your build
A hex bolt is a threaded fastener with a six-sided head designed to be driven with a wrench or socket. It clamps two or more components together under a controlled tension, holding assemblies rigid and preventing movement or loosening under vibration and load. When a bolt is the wrong length, stripped, or missing, the joint it is meant to secure can loosen over time, leading to misalignment, noise, or damage to the surrounding components — making like-for-like OEM replacement the straightforward choice for a lasting repair.
