The Honda 90042-Z6L-800 Stud Bolt is a genuine OEM replacement designed for GX630, GX660, GX690, GXV630, GXV660, and GXV690 engines. As a factory-sourced fastener, this stud bolt is manufactured to Honda's original specifications, ensuring the correct thread form, shank diameter, and engagement length for a proper, lasting installation. Honda supersedes fasteners at serial breaks, so confirm part number 90042-Z6L-800 against your engine's serial number in the fitment table before ordering.
Key Features
- Genuine OEM Honda Fastener — sourced directly from Honda, with thread specifications that match the original exactly, preventing cross-threading and maintaining correct clamp load
- Broad Engine Compatibility — listed for GX630, GX660, GX690, GXV630, GXV660, and GXV690 horizontal and vertical shaft engines; always verify your serial number against the fitment table to confirm the right stud bolt for your build
- Direct Drop-In Replacement — matches the original stud's dimensions, so installation requires no modification to the engine or mating components
A stud bolt is a headless fastener threaded at both ends: one end anchors permanently into a tapped bore in the engine casting, while the other end accepts a nut to secure the mating component. This two-piece arrangement allows covers, manifolds, or other components to be removed and refitted repeatedly without disturbing the threads in the casting itself. A stud bolt that is stretched, cross-threaded, or corroded can result in improper clamping, fastener failure, or damaged threads in the engine block — making timely replacement with the correct OEM part essential to keeping the engine properly assembled.
