Wacker Neuson 5000178379 M3X8 Screw

The Wacker Neuson M3X8 Screw is a genuine OEM fastener designed for the PSA2-1503L and PSA2-2203L submersible pumps. Sourced directly from Wacker Neuson, this screw meets the exact specifications of the original hardware used in production. It is a direct replacement for the PSA2 series, ensuring correct thread engagement and secure assembly without guesswork. Keep a spare on hand to avoid delays during routine service or component replacement.

Key Features

• Genuine OEM Thread Specification — M3X8 thread profile and length match the original production fastener exactly, ensuring full thread engagement and correct torque retention in the assembly.
• Direct-Fit Replacement — Installs in the same position as the original screw with no reworking of the mounting points or surrounding hardware.
• PSA2 Series Compatibility — Confirmed fitment for Wacker Neuson PSA2-1503L and PSA2-2203L submersible pumps.
• Maintains Structural Integrity — A correctly torqued fastener keeps mating components properly secured; a worn, stripped, or missing screw can allow movement, vibration damage, or water ingress in a submersible application.
• Corrosion-Resistant Application — Designed for use in the wet, submerged environment of a submersible pump where fastener integrity is critical to long-term housing and seal performance.

The M3X8 Screw is a metric fastener used to secure components within the pump housing or internal assembly of the PSA2 series submersible pump. In a submersible pump application, every fastener plays a role in keeping the housing sealed and internal parts properly aligned under continuous exposure to water and pressure. A stripped, corroded, or missing screw can compromise the clamping force between mated surfaces, potentially allowing movement or leakage that degrades pump performance over time. Replacing worn or damaged hardware with the correct OEM fastener restores the assembly to its original specification.
