The Wacker Neuson is a genuine OEM Screw M4 X 20 Cheese Head designed for the ES52Y electric rammer series, ES45Y electric rammer, and GS5.5A portable generator. As a direct factory replacement, this fastener is sourced from Wacker Neuson and matches the original specification used in production. Fitment spans multiple ES-series electric rammer configurations, including both 230V and 115V variants of the ES52Y, making it a versatile hardware pick for shops and service technicians supporting these machines. Verify your model number against the compatibility list before ordering to ensure a correct match.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact thread class and head geometry specified by Wacker Neuson, ensuring correct torque transfer and secure seating in the original threaded bosses.
- Cheese Head Profile — The cylindrical, flat-topped cheese head design provides a broad bearing surface and straight-sided slot drive, allowing controlled tightening in confined panel and housing locations.
- M4 X 20 Specification — Metric M4 thread diameter and 20 mm length match the original hardware dimensionally, dropping directly into existing threaded bores without re-tapping or adapting.
- Broad ES-Series and Generator Coverage — Fits the ES52Y electric rammer (230V and 115V), ES45Y electric rammer, and GS5.5A portable generator, covering a range of common Wacker Neuson compact equipment.
- Prevents Loose Assemblies — A missing or damaged fastener in a rammer or generator housing can allow panels and components to shift under vibration, leading to accelerated wear or electrical clearance issues; this replacement restores the correct clamping load.
The Screw M4 X 20 Cheese Head is a metric fastener used to secure panels, housings, or internal component brackets on compatible Wacker Neuson equipment. The cheese head style — characterized by its wide, low-profile cylindrical head — distributes clamping force evenly and resists pull-through in sheet metal and molded housings, which is why it is specified in locations subject to operational vibration. When this fastener is stripped, missing, or substituted with an incorrect size, the assembly it holds can loosen over time, potentially allowing moisture ingress, electrical component movement, or structural misalignment in the machine.
