The Honda 90302-758-U00 Flange Nut (0.25") is a genuine OEM fastener designed for BK4542 and BK4546 lawn tractors. As a direct Honda OEM part, it is manufactured to the same specifications as the original hardware it replaces. This part is listed for both the BK4542 and BK4546 — verify the part number 90302-758-U00 against your machine's parts diagram to confirm the correct application before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, ensuring the correct thread pitch, flange diameter, and seating dimensions for the original application
- Direct OEM Replacement — this is the same part installed at the factory, so it installs without modification into the positions where it is called out in the BK4542 and BK4546 parts diagram
- Flange Design — the integrated flange distributes clamping load across a wider bearing surface, reducing the chance of fastener loosening under vibration
- Check Your Serial Number — Honda supersedes hardware at production breaks; confirm part number 90302-758-U00 against your tractor's serial number in the fitment table before adding to cart
A flange nut combines a standard hex nut with a wide, integral flange that acts as a built-in washer. The flange spreads the clamping force over a larger surface area, which helps keep the fastener seated securely even under the vibration and load cycling that lawn tractor operation produces. When a flange nut is worn, damaged, or missing, the joint it secures can loosen over time, leading to component movement or potential hardware loss during use.
