Key Features
- Genuine Honda OEM Fastener — sourced directly from Honda, this tapping screw meets the exact size and thread specification used in original generator assembly.
- Correct 5X18 Sizing — the 5 mm diameter and 18 mm length are the defining specs buyers need to match; verify both against your application before ordering.
- Broad Generator Compatibility — listed for more than two dozen Honda generator models spanning the EB, EG, EM, EN, ES, EX, and EZ series; check your serial number against the fitment table to confirm your specific unit.
- Direct OEM Replacement — replaces the original fastener without reworking the receiving material, since a tapping screw cuts its own thread on first installation.
A tapping screw is a self-threading fastener that cuts its own mating thread into the receiving material as it is driven in, eliminating the need for a pre-tapped hole or a separate nut. In Honda generators, tapping screws like this one are used to secure covers, panels, and housings that make up the generator's outer structure. When an original screw is stripped, lost, or damaged, replacing it with the correct OEM fastener — matching diameter, length, and thread form — ensures the panel or cover it secures seats properly and stays in place during operation.
