The Honda 90101-ZB4-811 Flange Bolt (6X135) is a genuine OEM fastener designed for the EW140 welder generator, EZ3500 generator, and EZ5000 generator. As a direct Honda OEM part, it is manufactured to the same specification as the original hardware that left the factory. This bolt is listed for all three machines — confirm part number 90101-ZB4-811 against your unit's serial number and Honda parts diagram before ordering to ensure you have the correct fastener for your application.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this flange bolt meets the same dimensional and mechanical specification as the original fastener it replaces.
- Integrated Flange Design — the built-in flange distributes clamping load evenly, eliminating the need for a separate flat washer and maintaining consistent holding force.
- Broad Generator Fitment — listed for EW140 welder generators, EZ3500 generators, and EZ5000 generators; verify your serial number against the fitment table to confirm the correct part for your machine.
A flange bolt combines a standard hex-head bolt with an integrated wide-diameter flange at the base of the head, which acts like a built-in washer. This design spreads the clamping force across a larger surface area, reducing the risk of the fastener pulling through or loosening under vibration — a common concern on generators and welder generators that run for extended periods. When a fastener of this type wears, strips, or goes missing, the joint it secures can work loose, leading to misalignment or damage to the components it holds together.
