The Honda 93892-05020-08 Screw Washer (5X20) is a genuine OEM fastener designed for GX140, GX160, and GX200 horizontal shaft engines and the ES3500 generator. As a direct Honda OEM component, this screw-washer combination carries the exact dimensions and thread specification Honda engineering requires, so it drops straight in without any guesswork. Honda supersedes parts at serial breaks, so confirm your machine's serial number against the fitment table before ordering. This part ships as a single piece — order the quantity you need for your repair.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this screw washer meets the dimensional and thread specifications Honda set for these applications, giving you the correct fastener the first time.
- Integrated Washer Design — the captive washer distributes clamping load evenly across the mating surface, maintaining consistent pull-down without a separate loose washer to manage during assembly.
- Broad Fitment — listed for GX140, GX160, and GX200 horizontal shaft engines as well as the ES3500 generator; verify your serial number against the fitment table to confirm the correct application.
- Correct Thread and Length — the 5 x 20 designation identifies this screw's thread size and shank length; using the right fastener prevents cross-threading and stripped bores that can turn a simple service job into a costly repair.
A screw washer is a fastener with a permanently attached or formed washer flange at its head. Where a standard screw concentrates clamping force under a small head face, the integrated washer spreads that load across a wider area, reducing the risk of pull-through or surface damage on the panels, covers, and housings it secures. When this fastener is missing, damaged, or replaced with an incorrect substitute, the assembly it holds can work loose under vibration, leading to rattles, misalignment, or component damage over time.
