The Wacker Neuson is a genuine OEM Screw M5X12 S Torx designed for the EHB 7 series SDS-max electric demolition and rotary hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. As a direct OEM replacement, part is manufactured to the exact thread pitch, head profile, and drive specification required by these machines — no guesswork on fitment. Sourcing a genuine Wacker Neuson fastener ensures the correct clamping torque is achieved and maintained across the assembly it secures. When hardware like this wears, strips, or goes missing, replacing it with the correct spec part keeps the hammer running as intended.
Key Features
- Correct Torx Drive Specification — M5X12 sizing with an S Torx head profile matches the OEM tooling requirement exactly, ensuring proper installation torque without rounding or slippage.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this fastener meets the original material grade and thread tolerance used in production assembly.
- EHB 7 Series Compatibility — Confirmed fitment across the EHB 7M, EHB 7/115, and EHB 7/230 SDS-max electric demolition hammers, covering both 115V and 230V variants.
- Maintains Structural Integrity — Fasteners in demolition hammers are subject to significant vibration and impact loads; using the correct grade hardware preserves the clamping force that holds critical assemblies together.
- Electrical Safety Relevance — On electric-powered tools, improperly torqued or incorrect hardware near internal assemblies can compromise housing integrity and grounding paths — using the OEM-specified fastener matters for safe operation.
A Screw M5X12 S Torx is a metric fastener with an M5 thread diameter, 12 mm length, and a Torx (star-drive) head form. In a demolition hammer like the EHB 7 series, fasteners of this type are used to secure housings, internal components, and assemblies that must withstand constant high-frequency vibration and impact forces. When a fastener loosens, strips, or breaks, the assembly it holds can shift or separate, leading to accelerated wear on surrounding components or a loss of structural rigidity in the tool body. Replacing a damaged or missing fastener with the correct OEM part — right thread, right length, right drive — restores the assembly to its designed clamping specification and prevents cascading damage.
