The Honda 93893-04030-18 Screw-Washer (4X30) is a genuine OEM fastener designed for a wide range of Honda vertical shaft engines and snow blowers. This part is sourced directly from Honda and is the correct OEM specification for GXV270 and GXV340 vertical shaft engines, as well as HS520, HS521, HS621, HS55, HS80, HS828, HS928, HS1132, and HS1332 snow blowers. Because Honda supersedes fastener part numbers at production breaks, confirm the part number 93893-04030-18 against your machine's serial number in the fitment table before ordering. Ordering genuine Honda hardware keeps every assembly it secures performing exactly as designed.
Key Features
- Genuine OEM Honda Fastener — supplied directly from Honda with the correct thread form, shank length, and integrated washer geometry for the assemblies it secures on these engines and snow blowers.
- Broad Fitment — listed for GXV270 and GXV340 vertical shaft engines, and for HS520, HS521, HS621, HS55, HS80, HS828, HS928, HS1132, and HS1332 snow blowers; verify your serial number against the fitment table to confirm applicability to your specific unit.
- Exact OEM Dimensions — the 4X30 designation specifies the thread size and length; using the correct size matters where clamping load and assembly clearance are engineered to Honda's own tolerances.
A screw-washer is a fastener that combines a machine screw and an integrated washer in a single piece. The washer flange distributes clamping load across a broader area than a plain screw head, reducing the risk of the fastener pulling through or deforming softer housings and covers. When a screw-washer is lost, incorrectly sized, or substituted with a plain screw, the assembly it secures may work loose over time, leading to vibration damage or misalignment of the component it retains.
