The Wacker Neuson Special Screw is a genuine OEM fastener 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 special screw ensures an exact match to the original hardware used during assembly, maintaining the structural integrity of your hammer. It is the correct replacement when the original fastener is damaged, stripped, or lost during service. If you are servicing any EHB 7 series hammer, verifying part number against your machine's parts diagram confirms this is the right screw for your application.
Key Features
- Genuine OEM Specification: — Manufactured to the same thread form, head profile, and material grade as the original factory-installed fastener, ensuring proper torque retention in a high-vibration demolition tool environment.
- Drop-In Hardware Replacement: — Matches the original mounting position exactly, so reassembly proceeds without chasing threads or sourcing substitute hardware.
- Broad EHB 7 Series Coverage: — Compatible across the EHB 7M, EHB 7/115 (115V), and EHB 7/230 (230V) SDS-max rotary demolition hammers.
- Critical Fastener Integrity: — A worn or incorrect screw in a demolition hammer housing can allow internal components to shift under impact load, leading to accelerated wear or outright failure of adjacent parts.
- Electrical Safety Relevance: — Because the EHB 7 series are electric-powered tools, correctly torqued and specified fasteners help maintain housing closure and protect internal wiring from vibration-induced contact, supporting safe operation.
A special screw in a rotary demolition hammer is a purpose-engineered fastener that differs from standard hardware in thread form, head geometry, material grade, or shank profile to meet the specific demands of that assembly point. In a high-impact tool like the EHB 7 series, these fasteners hold housing sections, internal mechanisms, or accessory retention components together under continuous percussive stress. Using an incorrect or worn fastener risks loosening under load, which can allow housing panels to separate or internal components to move out of alignment, compromising both tool performance and operator safety.
