The Honda 90032-ZB4-811 Tapping Screw (4X10) is a genuine OEM fastener designed for Honda EN-series generators and EW-series welder generators. As a direct Honda OEM replacement, this screw matches the original specification used on the EN2000, EN2500, EN3500, and EN5000 generators as well as the EW140, EW171, and EXW171 welder generators. Honda supersedes hardware at serial breaks, so verify your unit's serial number against the fitment table before ordering to confirm part number 90032-ZB4-811 is correct for your machine.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this tapping screw meets the same specification as the original fastener installed at the factory.
- Correct Thread Form for Self-Tapping Applications — the 4X10 designation identifies the thread size and length exactly, ensuring the screw cuts and seats properly in its receiving material without stripping or overdriving.
- Broad Generator and Welder Generator Coverage — listed for the EN2000, EN2500, EN3500, EN5000, EW140, EW171, and EXW171, including both conventional generators and welder generator models.
- Serial Number Verification Recommended — Honda updates hardware part numbers across production runs, so check your machine's serial number against the fitment table to confirm this is the right screw for your unit.
A tapping screw is a self-threading fastener that forms its own mating threads as it is driven into the receiving material, eliminating the need for a pre-tapped hole. On Honda generators and welder generators, tapping screws are used to secure covers, panels, and housings that make up the machine's outer structure. When the original screw is lost, stripped, or damaged, replacing it with the correct OEM part ensures the panel or cover seats flush and stays secured during operation — an incorrect size can strip the receiving material or leave a fitting loose.
