The Honda 90045-ZG1-770 Stud Bolt (6X25) is a genuine OEM replacement fastener designed for Honda EB2500, EB3000, EM2500, and EM3000 generators, the EU3000 inverter generator, and the HP250 power carrier. As a direct Honda OEM component, this stud bolt is manufactured to the exact dimensions and thread specification of the original, ensuring a correct fit without the guesswork of aftermarket substitutes. Verify the part number 90045-ZG1-770 against your machine's serial number and Honda parts diagram before ordering, as Honda supersedes fastener part numbers at production breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, matching the original thread pitch, shank length, and diameter specified for these machines
- Exact Dimensional Fit — the 6X25 designation identifies the thread diameter and shank length, so this stud bolt installs directly into the original threaded bore without reworking
- Broad Model Coverage — listed for the EB2500, EB3000, EM2500, EM3000, EU3000, and HP250; confirm your unit's serial number against the fitment table to ensure this is the correct supersession for your production run
- Secure Clamping Retention — a correctly fitted stud bolt maintains proper clamping load across the joint it serves, preventing loosening under the vibration and thermal cycling these machines experience in regular use
A stud bolt is a headless fastener threaded at both ends: one end anchors into a tapped bore in the component housing, and a nut tightens onto the projecting end to clamp a mating part in place. This design is common in Honda generators and power equipment where a component must be removed and reinstalled repeatedly during service, since the stud remains in place and guides the mating part into alignment. When a stud bolt is cross-threaded, stretched, or corroded beyond use, it must be replaced to restore correct clamping and prevent joint movement during operation.
