The Honda 92900-08028-0B Stud Bolt (8X28) is a genuine OEM fastener designed for GD320 and GD410 horizontal shaft diesel engines and GV400 vertical shaft engines. As a direct Honda OEM component, this stud bolt carries the exact thread pitch, shank diameter, and length specified for these engines, ensuring the joint it serves clamps down the way Honda engineered it to. This part fits across three distinct engine lines, so confirm your engine's serial number against the fitment table before ordering to make sure part number 92900-08028-0B corresponds to your specific unit.
Key Features
- Genuine Honda OEM Fastener — sourced directly from Honda, this stud bolt meets the exact thread and dimensional specifications required for secure, properly torqued joints on GD320, GD410, and GV400 engines
- Correct Engagement Length — the 8X28 designation specifies an 8 mm thread diameter and 28 mm length; using the wrong stud risks under-clamping or thread stripping, making an exact match critical
- Broad Engine Compatibility — listed for GD320 and GD410 horizontal shaft diesel engines as well as the GV400 vertical shaft engine; verify your serial number against the fitment table before ordering
- Maintains Joint Integrity — a worn, stretched, or damaged stud bolt can lead to loose assemblies, gasket failure, or fluid leaks; replacing with the correct OEM part restores the clamping load Honda designed for
A stud bolt is a headless threaded fastener that is anchored into a tapped bore at one end, with the exposed threaded end accepting a nut. This design allows a mating component — such as a cover, flange, or manifold — to be drawn down evenly and removed repeatedly without disturbing the base thread in the engine casting. When a stud bolt becomes stretched, corroded, or cross-threaded, it can no longer develop the clamping force needed to keep the joint sealed under operating loads, making timely replacement with the correct part essential for keeping the engine running as intended.
