Key Features
- Genuine Honda OEM Part — sourced directly from Honda.
- Integrated Washer Design — the combined screw and washer construction distributes clamping load evenly, eliminating the need for a separate flat washer and reducing the chance of a missing component during reassembly.
- Broad Fitment Coverage — listed for Honda generators including the EB3000 and EM4000, GX360 and GX640 horizontal shaft engines, EW170 welder generator, EV-series RV generators, and H- and HT-series lawn and multi-purpose tractors.
- Verify Before Ordering — Honda updates hardware across serial number breaks, so confirm your model and serial number against the fitment table to ensure part number 90092-657-000 is correct for your specific unit.
A screw-washer is a single captive fastener that combines a threaded screw with an integrated washer flange. The washer portion spreads the clamping force over a wider surface area than a bare screw head alone, helping panels, covers, and components seat firmly without crushing or distorting the material beneath. When a screw-washer works loose or goes missing, the component it secures can shift, vibrate, or come free entirely — making timely replacement with the correct OEM hardware an important part of routine maintenance and reassembly.
