The Honda 93892-04008-08 Screw-Washer (4x8) is a genuine OEM fastener designed for a wide range of Honda generators, the GX360 horizontal shaft engine, and the HR21 lawn mower. As a factory-original component, this screw-washer is manufactured to Honda's exact dimensional tolerances, ensuring a correct fit across every listed application. Because Honda supersedes fastener part numbers at production breaks, confirm your unit's serial number against the fitment table before ordering. This is a direct OEM replacement sourced through Honda's authorized parts network.
Key Features
- Genuine OEM Fastener — factory-original screw-washer combining a threaded fastener and integrated washer in a single piece, maintaining the correct clamping characteristics Honda specifies for these assemblies
- Broad Honda Compatibility — listed for Honda generators including the E4500, EB2200, EB2500, EB3000, EB4000, EL5000, EM-series, EMS-series, ES-series, and EX-series models, as well as the GX360 horizontal shaft engine and HR21 lawn mower
- Check Your Serial Number — Honda updates fastener specifications at serial number breaks, so verify your unit's serial against the fitment table to confirm part number 93892-04008-08 is correct for your machine
- Exact 4x8 Dimension — the 4x8 size designation identifies this specific variant; match it to your existing hardware to avoid ordering the wrong screw-washer for your application
A screw-washer is a combined fastener that integrates a machine screw with a captive washer flange, distributing clamping load across a broader surface area than a plain screw alone. This design helps secure panels, covers, and components without the risk of the washer falling free during assembly or service. When the original fastener is lost, stripped, or corroded, replacing it with the correct OEM screw-washer restores the proper clamping force and keeps the assembly seated as Honda intended.
