Key Features
- Genuine OEM Specification — manufactured to Honda's exact thread pitch and length, ensuring proper clamping load and thread engagement on the GXR120 engine
- Exact Dimensions — the (5X110) designation identifies a 5 mm threaded stud at 110 mm length; match this to your parts diagram before ordering
- Direct OEM Replacement — backed by part number 90042-ZDJ-820 for confident cross-referencing against Honda's own parts catalogue
A stud bolt is a fully threaded or partially threaded fastener that threads into a fixed component on one end, with a nut applied to the projecting end to clamp a mating part in place. On the GXR120 horizontal shaft engine, stud bolts provide the consistent, repeatable clamping force that keeps critical engine assemblies properly seated. A stud that is stripped, corroded, or incorrectly sized can result in loose assemblies, gasket failure, or misalignment — making an exact-fit replacement essential for keeping the engine operating as Honda intended.
