The Honda 90004-ZL8-000 Flange Bolt (6X79) is a genuine OEM fastener used across a wide range of Honda engines, lawn mowers, snow blowers, water pumps, tillers, and generators. As a direct Honda OEM replacement, this bolt is manufactured to the same specifications as the original hardware — correct thread pitch, shank length, and integrated flange geometry — so it seats and clamps exactly as intended. This part is listed for a broad range of Honda equipment including GC135, GC160, GC190, GCV135, GCV160, GCV170, GCV190, GCV200, GS160, GS190, GSV190, GXR120, HRB216, HRB217, HRC216, HRN216, HRR216, HRS216, HRT216, HRX217, HRZ216, HS520, HS720, WN20, WN30, FG400, FG500, EN2000, EN2500, EB2800, and EG2800. Because Honda supersedes fasteners at serial breaks, always verify your unit's serial number against the fitment table before ordering to confirm part number 90004-ZL8-000 is the correct bolt for your specific machine.
Key Features
- Genuine Honda OEM Hardware — produced to Honda's original tolerances for thread form and flange bearing surface, ensuring correct clamping load without the guesswork of sourcing a generic substitute.
- Integrated Flange Design — the captive flange distributes clamping force over a wider bearing area, reducing the risk of fastener loosening under vibration without needing a separate washer.
- Broad Cross-Equipment Fitment — listed for horizontal and vertical shaft engines, walk-behind lawn mowers, single-stage snow blowers, water pumps, tillers, and generators including GC, GCV, GS, GSV, and GXR120 series units, among others.
- Verify Serial Number Before Ordering — Honda parts are superseded at specific serial breaks; check your machine's serial number against the fitment table to confirm this is the correct bolt for your unit.
A flange bolt combines a standard hex-head bolt with a built-in washer-like flange at its base. The flange spreads the clamping load across a larger surface area than a plain bolt head alone, which helps keep fastened components secure even under the continuous vibration that engines and outdoor power equipment produce. When a flange bolt stretches, strips, or goes missing, the joint it held can loosen progressively, leading to misalignment, increased wear on mating parts, or component separation during operation. Replacing a worn or damaged bolt with the correct OEM part restores the original clamping integrity and keeps the assembly performing as designed.
