The Wacker Neuson is a genuine OEM Screw M4X18 Torx K designed for the EHB 7 series electric rotary demolition hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. Sourced directly from Wacker Neuson, this fastener matches the exact thread pitch, head profile, and Torx K drive specification of the original hardware used at the factory. Replacing a stripped, damaged, or missing screw with the correct OEM part ensures housing panels and internal components are secured to the right torque spec and stay that way under continuous vibration and impact loads.
Key Features
- Torx K Drive Specification: — Matches the tamper-resistant Torx K head profile specified for the EHB 7 series, ensuring the correct driver tool engagement and proper installation torque.
- M4X18 Thread and Length Match: — Correct M4 thread pitch and 18mm length drops straight into the existing threaded bosses without recutting or shimming.
- Genuine OEM Part: — Manufactured to the same material grade and surface treatment as the original fastener, resisting loosening under the high-frequency vibration that SDS-max demolition hammers generate continuously.
- Broad EHB 7 Series Coverage: — Confirmed fitment across EHB 7M, EHB 7/115, and EHB 7/230 variants, covering both 115V and 230V configurations of Wacker Neuson's SDS-max rotary demolition hammer line.
- Structural Integrity Under Impact: — A correctly torqued fastener keeps housing sections and internal assemblies aligned; a loose or missing screw can allow cover flex, component shifting, and accelerated wear on surrounding parts.
The Screw M4X18 Torx K is a structural fastener used to secure housing panels or internal subassemblies on the EHB 7 series electric demolition hammers. On a high-vibration tool like an SDS-max rotary hammer, every fastener is under constant cyclic stress, and even a single missing or under-torqued screw can allow housing sections to shift, creating gaps that admit dust and debris while accelerating wear on gaskets and adjacent components. Replacing the 5000104238 with a genuine OEM screw ensures the correct clamping load is achieved and maintained throughout the tool's service life.
