The Honda 90002-ZM7-000 Stud Bolt (5X55) is a genuine OEM fastener designed for GXH50 horizontal shaft engines, GXV50 and GXV57 vertical shaft engines, and WX15 water pumps. As a direct Honda OEM component, this stud bolt is produced to the exact dimensions specified for these applications, ensuring correct thread engagement and clamp load where it counts. Confirm fitment against your machine's serial number before ordering, as Honda periodically supersedes hardware at production breaks. Part number 90002-ZM7-000 is the correct reference to use when cross-checking your Honda parts diagram.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this stud bolt meets the exact thread pitch, shank length, and diameter called out in the original parts diagram — no guesswork on sizing.
- 5 x 55 mm Specification — the (5X55) designation identifies the precise variant; verify this matches your application before ordering, particularly where multiple stud lengths are listed for the same model.
- Broad Fitment — listed for GXH50 horizontal shaft engines, GXV50 and GXV57 vertical shaft engines, and WX15 water pumps; check your serial number against the fitment table to confirm the correct part for your production run.
- Consistent Clamping Load — a correctly specified stud bolt maintains the designed clamping load on the joint it secures; an incorrect length or pitch can lead to joint movement or inadequate retention over time.
A stud bolt is a headless threaded fastener that threads into a tapped bore on one end while a nut is applied to the exposed end, creating a stable, repeatable clamping arrangement. This design allows components to be removed and reinstalled without disturbing the thread in the base material, which is especially useful in aluminum engine and pump housings where thread preservation matters. When a stud bolt is damaged, stretched, or replaced with an incorrect size, proper joint integrity cannot be achieved and the assembled components may not seat or seal as intended.
