The Wacker Neuson Nut is a genuine OEM Nut designed for the EHB 7 series electric demolition hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. As a direct OEM part, it is manufactured to the exact specifications required by these SDS-max rotary demolition hammers, ensuring a correct, secure fit every time. This is the same nut supplied on new machines, so there is no guesswork involved in matching hardware grades or thread dimensions. If you are servicing any model in the EHB 7 family, part number is the verified replacement to use.
Key Features
- Exact OEM Thread Specification — Manufactured to the precise thread pitch and grade required for the EHB 7 series, so the fastener seats and torques correctly without risk of stripping or cross-threading.
- Direct Drop-In Fit — Engineered to the same dimensional profile as the original hardware, allowing straightforward installation during service or rebuild without additional fitting work.
- Confirmed EHB 7 Series Compatibility — Verified fitment across the EHB 7M, EHB 7/115, and EHB 7/230 electric demolition hammer models.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same material and hardness specification as the original component used on the production line.
- Maintains Structural Integrity Under High-Impact Operation — Demolition hammers transmit significant vibration and impact force through every fastener; a correctly spec'd nut keeps critical assemblies secure and prevents progressive loosening during heavy use.
A nut in an electric demolition hammer like the EHB 7 series plays a critical role in securing internal and external assemblies that must withstand continuous high-frequency impact forces. Fasteners in this environment are subject to vibration-induced loosening, which can lead to component misalignment, accelerated wear on surrounding parts, or loss of function if left unaddressed. Using the correct OEM-grade nut — part number 5000104178 — ensures the hardware holds to the correct torque specification and maintains the structural integrity of the assembly throughout the tool's service life.
