The Honda 90043-Z6L-000 Stud Bolt (6X106) is a genuine OEM fastener designed for Honda GX630, GX660, GX690, GXV630, GXV660, and GXV690 engines. As an authentic Honda part, it is manufactured to the same specification as the original hardware installed at the factory. This stud bolt is listed across both the GX horizontal shaft and GXV vertical shaft variants of Honda's large-displacement engine lineup, so verify your engine model and serial number against the fitment table before ordering to confirm this is the correct part for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, ensuring the thread form, shank length.
- Correct 6X106 Sizing — the (6X106) designation identifies this as a 6 mm diameter, 106 mm length stud; match this to your existing hardware before ordering
- Broad Engine Coverage — listed for GX630, GX660, GX690, GXV630, GXV660, and GXV690 engines, spanning both horizontal and vertical shaft configurations in Honda's large-displacement range
- Confirm by Serial Number — Honda supersedes fasteners at production breaks, so cross-reference your engine's serial number against the fitment table to confirm part number 90043-Z6L-000 is correct for your serial range
A stud bolt is a headless fastener threaded at both ends — one end anchors into a tapped bore in the engine casing, and a nut runs down the exposed end to clamp a cover, bracket, or assembly in place. This design allows a component to be removed and refitted repeatedly without disturbing the threads in the casting itself. When a stud bolt becomes stretched, corroded, or cross-threaded, clamping force is lost and the joint it secures can work loose, leading to leaks or component movement. Replacing a damaged stud with the correct OEM part restores proper clamping load across the joint.
