The Honda 92800-12000 Drain Plug Bolt (12MM) is a genuine OEM fastener designed for a wide range of Honda engines, generators, tillers, lawn tractors, and riding mowers — including GX120, GX160, GX200, GX240, GX270, GX390, and GX640 horizontal shaft engines, G-series engines, GV35 vertical shaft engines, GS65 horizontal shaft engines, E-series and EB, EG, EL, EM, ER, ES, EX, and EV-series generators, RV generators, F-series tillers, and H-series lawn and multi-purpose tractors. As a genuine Honda part, it is manufactured to the exact thread specification and head dimensions Honda engineers specified for these machines. Because this bolt spans a broad range of Honda equipment across multiple product lines, confirm the part number 92800-12000 against your machine's serial number and parts diagram before ordering.
Key Features
- Genuine Honda OEM Fastener — manufactured to Honda's exact thread pitch and dimensions, so the drain plug seats and seals correctly every time oil is changed.
- Correct Thread Specification — the 12MM designation identifies a specific thread size; using the wrong bolt risks stripping the drain port or allowing an oil leak at the sump.
- Broad Honda Fitment — listed for GX-series horizontal shaft engines, G-series and GS65 engines, GV35 vertical shaft engines, E-, EB, EG, EL, EM, ER, ES, EX, and EV-series generators, RV generators, F-series tillers, and H-series tractors and riding mowers, including models such as GX160, GX390, EM5000, EV4010, and H5013.
- Verify Your Serial Number — Honda supersedes fasteners across production runs, so check your machine's serial number against the fitment table to confirm this is the correct drain plug bolt for your unit.
A drain plug bolt seals the oil drain port at the base of the sump or crankcase, keeping engine or equipment oil contained between service intervals. At each oil change, this bolt is removed to drain used oil and then reinstalled to close the port before fresh oil is added. A bolt with worn threads, the wrong thread pitch, or an incorrect seating surface will not seal reliably, resulting in oil loss that can lead to rapid internal wear or engine failure if left undetected.
