The Honda 90031-ZB4-811 Tapping Screw (5X8) is a genuine OEM fastener designed for the EW140 and EW171 welder generators. As a direct Honda OEM part, it is manufactured to the same specification as the original hardware installed at the factory. Confirm the part number 90031-ZB4-811 against your unit's serial number and parts diagram before ordering, as Honda supersedes fasteners at production breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this tapping screw matches the thread form, head size, and drive type of the original hardware used in EW140 and EW171 welder generators.
- Exact Dimensional Fit — the 5X8 sizing ensures this screw threads correctly into its designed location without the guesswork that comes with sourcing a generic substitute.
- Welder Generator Application — listed for the EW140 and EW171 welder generators; verify your unit's serial number against the fitment table to confirm this is the correct screw for your production range.
A tapping screw cuts or forms its own threads as it is driven into a pre-drilled or punched hole in sheet metal or plastic panels. In a welder generator such as the EW140 and EW171, these screws are used to secure covers, panels, and housings that protect the internal components of the unit. Using the correctly sized OEM screw ensures the joint clamps properly and that the threads are not stripped or mismatched, which can leave covers loose or difficult to remove during future servicing.
