The Honda 93500-05020-0A Pan Head Screw (5x20) is a genuine OEM fastener used across a wide range of Honda engines, power equipment, and outdoor power machines, including GXH50 and GXV-series engines, HR-series lawn mowers, WA- and WB-series water pumps, and select generators and tillers. As a direct Honda OEM part, this screw matches the exact dimensions specified for the applications it serves — 5 mm diameter, 20 mm length, pan head profile. Because this screw appears in the parts lists of many different Honda machines, always confirm your specific model and serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda and manufactured to the same dimensional specifications as the original hardware, ensuring the correct thread pitch, head profile, and shank length for a proper installation.
- Correct 5x20 Specification — the 5 mm x 20 mm pan head form is a specific callout in Honda's parts catalog; substituting an incorrect length or head style can result in improper clamping or interference with surrounding components.
- Broad Fitment Across Honda Equipment — listed for GXH50 and GXV-series engines, HR- and HRC-series lawn mowers, H-series riding mowers, WA-, WB-, WD-, and WX-series water pumps, F-series tillers, select generators, and the HP400 power carrier, among others.
- Verify Your Serial Number — Honda updates hardware specifications at production serial breaks; check your machine's serial number against the fitment table to confirm part number 93500-05020-0A is correct for your unit.
A pan head screw is a standard threaded fastener with a wide, low-profile dome head that distributes clamping load across the surface it contacts. In Honda equipment, fasteners like this one secure covers, panels, brackets, and housings throughout the machine. When a screw of the wrong length or thread is used in its place, components may not seat correctly, gaps can develop, and vibration during operation can cause additional wear or loosening over time. Using the correct OEM-specified screw ensures the joint holds to Honda's original design intent for the service life of the equipment.
