Key Features
- Genuine OEM Honda Hardware — sourced directly from Honda, this bolt matches the original specification for thread form, head size, and length (10X250), ensuring it seats and torques correctly in the generator assembly.
- Broad Generator Compatibility — listed for Honda EB, EG, EM, and EX series generators including the EB3800, EB4000, EB5000, EB6500, EG5000, EG6500, EM3800, EM4000, EM5000, EM6500, and EX4500.
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production breaks; confirm your unit's serial number against the fitment table to ensure part number 90021-ZC2-000 is correct for your specific generator.
This Hexagon Bolt (10X250) is a structural fastener used within Honda's conventional generator lineup. Fasteners of this length are typically called upon to secure major assemblies or panels where a long clamping reach is required. A missing, damaged, or incorrect bolt in these positions can compromise the integrity of the assembly it holds; replacing it with the correct OEM part restores the proper clamping load and keeps the generator operating as Honda intended.
