The Honda 93903-25220 Tapping Screw (5X12) is a genuine OEM fastener designed for EU1000, EX350, and EX700 inverter generators, as well as H4013, H4514, H4518, and H5518 lawn and multi-purpose tractors. As a factory-original component, this screw is manufactured to Honda's exact dimensional and thread specifications, ensuring it seats and drives correctly without the guesswork that can come with generic hardware substitutions. Verify your model and serial number against the fitment table before ordering, as Honda updates part supersessions at specific serial breaks.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this tapping screw carries the exact thread form and head dimensions specified for these applications, ensuring consistent engagement and secure holding power
- Direct OEM Replacement — matches the original fastener's size and thread pitch for a straightforward swap with no re-tapping or modification of the surrounding material
- Broad Model Coverage — listed for EU1000, EX350, and EX700 inverter generators, and H4013, H4514, H4518, and H5518 lawn and multi-purpose tractors, including models across multiple serial ranges
- Serial Number Verification Recommended — Honda supersedes fastener specifications at serial breaks, so confirm your unit's serial number against the fitment table to ensure this is the correct screw for your machine
A tapping screw cuts or forms its own thread as it is driven into a pre-drilled hole in sheet metal, plastic housings, or similar panels and covers. Because it creates the thread on first installation, the screw's diameter and pitch must match the original exactly — an undersized replacement will strip out, and an oversized one will split or distort the surrounding material. Using the correct OEM screw maintains the holding integrity of the panel or component it secures and prevents the loosening or rattling that a mismatched fastener causes over time.
