The Honda 90154-750-881 Hexagon Bolt (5/16-18X3/4) is a genuine OEM fastener designed for the HT3810 lawn tractor. As a direct Honda OEM part, it is manufactured to the same specification as the original hardware, ensuring a proper fit without modification. Honda supersedes parts at serial breaks, so confirm your tractor's serial number against the fitment table before ordering. This bolt is an easy, like-for-like replacement when the original fastener is damaged, lost, or due for service.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this bolt matches the thread pitch, head size, and length of the original 5/16-18 x 3/4 fastener installed at the factory.
- Exact Dimensional Fit — the 5/16-18 x 3/4 specification ensures the bolt seats and torques correctly in the intended location on the HT3810 tractor.
- Serial Number Verification Recommended — Honda revises hardware specifications across production runs, so check your HT3810 serial number against the compatibility table to confirm this is the correct part for your unit.
A hexagon bolt is a standard threaded fastener used throughout the HT3810 lawn tractor to clamp and secure components in place. The 5/16-18 thread designation identifies its diameter and thread count per inch, while the 3/4-inch length determines how deep it engages the mating part. Using a bolt of the correct specification matters because an incorrect thread pitch or length can result in an insecure joint or a stripped thread, compromising the integrity of the assembly it holds.
