The Honda 93913-24780 Tapping Screw (4X30) is a genuine OEM fastener designed for GCV520, GCV530, GXV390, GXV520, and GXV530 vertical shaft engines. As a direct Honda OEM part, it meets the exact dimensional and thread specifications Honda engineers specified for these engines. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and listing coverage may vary by production range.
Key Features
- Genuine OEM Thread Integrity — cut to Honda's exact thread pitch and diameter, so it drives cleanly into its intended boss without cross-threading or under-torquing
- Direct OEM Replacement — sourced from Honda and identified by part number 93913-24780, eliminating any guesswork when restoring a fastener on the assembly
- Broad Vertical-Engine Coverage — listed for GCV520, GCV530, GXV390, GXV520, and GXV530 vertical shaft engines, covering a wide range of Honda's vertical-crankshaft line
- Serial Number Verification Recommended — Honda updates fastener specifications at production breaks, so cross-check your engine's serial number against the fitment table to confirm this is the correct screw for your unit
A tapping screw cuts its own thread as it is driven into a pre-drilled hole in a housing, cover, or panel. Because the screw forms the thread on its first installation, dimensional accuracy matters — an undersized or incorrectly pitched screw will not grip correctly, and an oversized one can split or strip the boss. On Honda vertical shaft engines, tapping screws are used in a variety of cover and component retention points; a failed or missing screw allows those components to loosen under vibration, potentially leading to misfits, oil or air leaks, or cover damage. Replacing a stripped or lost screw with the correct OEM part restores the clamping load the assembly was designed around.
