The Wacker Neuson M8 x 35 Bolt is a genuine OEM fastener designed for the PST2 400 and PST3 750 series submersible pumps. Sourced directly from Wacker Neuson, this bolt matches the exact thread pitch, grade, and dimensions specified for these pumps at the factory. Compatible across a wide range of PST2 400 and PST3 750 configurations — including 110 V and 230 V variants — this part covers both the standard PST and float-switch PSTF models. When a fastener on your submersible pump loosens, corrodes, or strips, replacing it with the correct OEM bolt ensures the assembly stays secure and watertight under continuous pumping conditions.
Key Features
- Correct Thread and Grade Specification — M8 x 35 dimensions match the OEM specification exactly, so the bolt seats and torques correctly without risk of cross-threading or under-clamping.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component, part number 5000150721, ensuring material and dimensional conformance to the original design.
- Broad PST Series Coverage — Fits PST2 400 and PST3 750 submersible pumps across multiple voltage configurations (110 V and 230 V) and both standard PST and float-equipped PSTF variants.
- Maintains Pump Integrity Under Wet Conditions — A correctly specified fastener keeps pump housings and components clamped firmly, preventing vibration-induced loosening during continuous submerged operation.
- Direct Drop-In Replacement — Installs into the existing threaded location with no modification, making a worn or damaged fastener swap fast and straightforward on the job.
A fastener like the M8 x 35 Bolt plays a critical role in holding together the structural and housing components of a submersible pump. In a submerged environment, bolts are exposed to constant moisture and vibration, which can cause corrosion, fatigue, and eventual loosening over time. A failed or missing fastener compromises the mechanical integrity of the pump assembly, potentially allowing housing sections to separate and exposing internal components to water ingress — leading to pump failure or unsafe operation.
