The Honda 93913-25580 Tapping Screw (5X20) is a genuine OEM fastener designed for a wide range of Honda horizontal and vertical shaft engines as well as Honda EB-series generators. This screw is sourced directly from Honda and carries the exact dimensions and thread profile Honda specifies for these applications. Confirm your model and serial number against the fitment table before ordering, as Honda updates part listings at serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, carrying the exact thread form and head dimensions specified for part number 93913-25580.
- Broad Fitment — listed for Honda GX-series horizontal shaft engines including the GX240, GX270, GX340, GX390, GX440, GX610, GX620, GX630, GX660, GX670, GX690, GX700, and GX800; GXV-series vertical shaft engines including the GXV610, GXV620, GXV630, GXV660, GXV670, and GXV690; and EB10000 and EB11000 generators.
- Serial Number Verification Recommended — Honda supersedes fasteners at production breaks, so check your unit's serial number against the fitment table to confirm this is the correct screw for your machine.
- Self-Tapping Design — cuts its own thread on installation, allowing a secure, rattle-free hold without a separate nut or pre-tapped receiver.
A tapping screw is a self-threading fastener that forms its own mating thread as it is driven into the receiving material. Because it cuts rather than rolls into a pre-tapped hole, a correctly sized replacement screw is essential — an incorrect thread pitch or shank diameter will strip the receiver or fail to seat fully, resulting in loose panels, covers, or components. Using the OEM-specified screw for your Honda engine or generator ensures the joint clamps at the load Honda intended and holds securely through normal operating vibration.
