The Honda 90003-Z1L-000 Flange Bolt (6X86) is a genuine OEM fastener designed for the GCV160 vertical shaft engine. As a direct Honda replacement, this bolt is sourced to the exact specification Honda calls out for this application, so it threads in correctly and seats flush without guesswork. Confirm your engine's serial number against the fitment table before ordering to ensure this is the right variant for your production range.
Key Features
- Genuine OEM Fitment — sourced directly from Honda, carrying the same part number 90003-Z1L-000 called out in the Honda GCV160 parts catalog
- Correct Dimensions — the 6x86 size designation specifies both thread diameter and shank length, so this bolt engages threads fully and clamps at the designed load
- Built-In Flange — the integrated flange distributes clamping force across a wider bearing surface, eliminating the need for a separate washer and keeping the fastened joint secure under engine vibration
- Serial Number Verification Recommended — Honda updates parts at production breaks, so matching your GCV160 serial number to the fitment table confirms this is the correct bolt for your specific unit
A flange bolt combines a standard hex bolt with a wide, integral flange beneath the head that acts like a built-in washer. In the GCV160 vertical shaft engine, fasteners like this one secure components that must stay firmly in place through sustained vibration and thermal cycling. When a flange bolt is worn, stripped, or replaced with an incorrect size, clamping force drops, joints can work loose, and component damage or engine failure may follow — making an exact OEM replacement the straightforward choice.
