The Wacker Neuson Screw M12 X 324 Extended Shaft is a genuine OEM component designed for the BH 22, BH 23, BH 55, BH 65, EH 22, EH 23, EH 24, EH 27, and EH 50 series gasoline and electric breakers. As a factory-sourced part, the is manufactured to the exact dimensions and material specifications used in original production, ensuring a direct, dependable installation. This extended shaft screw serves a critical fastening role across a wide range of Wacker Neuson breaker configurations, covering multiple tool holder sizes and voltage variants. Confirm your model number against the fitment list before ordering to ensure you receive the correct replacement.
Key Features
- Exact Thread and Length Specification — M12 x 324 dimensions match the OEM-specified fastener precisely, maintaining correct clamping force and shaft alignment in the breaker assembly.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this screw is manufactured from the same material grade used in original production, not a generic substitute.
- Extended Shaft Design — The extended shaft profile is purpose-built for the tool holder and drive mechanism interfaces found across BH and EH series breakers, slotting in without modification to the surrounding hardware.
- Broad Breaker Compatibility — Fits a wide cross-section of Wacker Neuson petrol and electric breakers including BH 23, BH 55, BH 65, EH 23, EH 24, EH 27, and EH 50 series across multiple tool holder configurations (27x80, 25x108, 28x152, 28x160, 32x160).
- Structural Integrity Under Impact Load — Breaker fasteners are subjected to repeated high-frequency impact forces; using the correct OEM screw maintains the structural integrity of the tool holder connection and prevents premature loosening or fastener failure.
The Screw M12 X 324 Extended Shaft is a critical fastening component within the tool holder and drive shaft assembly of Wacker Neuson breakers. Its extended length allows it to span and secure the internal shaft components that transfer impact energy from the engine or motor down to the chisel or tool bit. When this screw becomes worn, damaged, or incorrectly replaced with a non-specified fastener, the tool holder connection can loosen under load, leading to imprecise tool engagement, accelerated wear on surrounding components, and potential operational failure during breaking work. Using the correct OEM replacement ensures the assembly maintains its designed clamping load and continues to perform safely under the demanding conditions of demolition and breaking applications.
