The Wacker Neuson M8 Nut is a genuine OEM fastener designed for the PST2 400, PS2 750, and PSTF2 400 series submersible pumps. Sourced directly from Wacker Neuson, this replacement nut matches the original hardware specification used in production, ensuring a correct and consistent fit within the pump assembly. The is the authorized replacement for all listed PST2 400 and PS2 750 variants, covering both 110V and 230V configurations across multiple machine numbers. Keep a spare on hand to avoid unnecessary service delays when performing routine maintenance or repairs on your submersible pump.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's original thread specification and material hardness for the M8 fastener position, so torque values and clamping load stay consistent with the designed assembly.
- Drop-In Hardware Replacement — Matches the original M8 thread pitch and dimensions used at the factory, threading directly onto existing studs or bolts without reworking mating components.
- Broad PST2 and PS2 Series Coverage — Compatible with PST2 400 (110V and 230V), PS2 750 (110V and 220V), and PSTF2 400 submersible pump models, making it a practical part to stock for mixed fleets.
- Maintains Structural Integrity of the Pump Assembly — A failed or stripped M8 nut can allow fastened components to shift or loosen under vibration, leading to misalignment, leaks, or accelerated wear on sealed pump housings.
- Authorized Wacker Neuson Part — Carrying part number 5000150745, this nut is supplied through the official Wacker Neuson parts network, so you can cross-reference it confidently against your service manual.
An M8 nut is a metric hex fastener used to secure components within the pump assembly, applying controlled clamping force to hold mating parts firmly in position. In a submersible pump environment, fasteners are exposed to constant moisture, vibration from the motor, and thermal cycling — conditions that accelerate corrosion and fatigue on hardware that does not meet the original material specification. When an M8 nut loosens, strips, or corrodes through, the components it secures can shift, compromising seals or bearing alignment and ultimately leading to pump failure or water ingress into the motor housing.
