The Wacker Neuson is a genuine OEM Bolt With Washer M8 X 20 designed for the PS2 500, PS2 800, PSA2 500, and PSA2 800 series submersible pumps. As a direct OEM component, is manufactured to the exact dimensions and material specifications used in original production, ensuring a correct fit into the pump's assembly without any guesswork. This fastener is confirmed compatible across a broad range of PS2 and PSA2 series pump configurations, including both standard and 230V variants. Having the right hardware on hand keeps your pump fully secured and operating as intended.
Key Features
- Integrated Washer Design — The captive washer is sized and positioned to distribute clamping load evenly, protecting the mating surface of pump housing components from damage during torquing.
- Genuine OEM Material Grade — Manufactured to the same tensile and corrosion-resistance standards as the original fastener, critical for a submersible application where hardware is routinely exposed to water and debris.
- M8 x 20 Specification — Exact thread pitch, diameter, and length match the original assembly requirements, so the bolt seats fully and engages the correct thread depth without modification.
- Broad PS2 and PSA2 Series Compatibility — Fits PS2 500, PS2 800, PSA2 500, and PSA2 800 submersible pumps across multiple machine configurations and voltage variants.
- Structural Integrity at the Pump Housing — A loose, stripped, or incorrect fastener at the pump housing can lead to misalignment, vibration damage, or ingress of water into sealed sections — using the correct OEM bolt prevents these failure modes.
The Bolt With Washer M8 X 20 is a structural fastener used to secure key housing or component assemblies on Wacker Neuson PS2 and PSA2 series submersible pumps. The integrated washer serves a dual purpose: it spreads clamping force across the bolt head contact area to prevent surface damage, and it helps maintain consistent torque retention under the vibration and wet conditions typical of submersible pump operation. When a fastener like this is worn, corroded, or missing, it can compromise the structural integrity of the pump assembly, leading to misalignment, leaks, or component movement that accelerates wear on surrounding parts.
