The Wacker Neuson Screw with Washer is a genuine OEM component designed for PT3A, PT4A, PT3A(I), and PT4A(I) series trash pumps. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original hardware used on the production line — no guesswork, no substitutions. It fits across multiple PT-series configurations, including the PT3A(I) and PT4A(I) models, making it a dependable choice for maintenance and repair work on these machines. Keep a verified OEM part number on hand to ensure your pump goes back together right the first time.
Key Features
- OEM Thread and Dimension Accuracy — Manufactured to the exact thread pitch, diameter, and head spec as the original, so the integrated washer seats flush and torques correctly every time.
- Integrated Washer Design — The captive washer distributes clamping load evenly across the mating surface, protecting the housing material from damage during installation and service.
- Broad PT-Series Fitment — Confirmed fit across PT3A, PT4A, PT3A(I), and PT4A(I) trash pump models, covering both standard and international variants in the lineup.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM replacement, carrying the same part number (5100044384) used in Wacker Neuson's own service documentation and parts catalog.
- Structural Integrity Under Vibration — A correctly spec'd screw and washer assembly holds critical panels and covers secure during high-vibration pump operation, preventing loosening that can lead to misalignment or component damage.
A screw with washer assembly is a hardware fastener that secures covers, housings, or structural panels on the pump, with the integrated washer serving to spread the load of the fastener head across the surface being clamped. While it may appear to be a minor component, using the correct screw — with the right thread form, length, and washer size — is essential to maintaining proper torque retention on assemblies that experience continuous vibration during operation. When a screw wears, strips, or goes missing, the component it secures can shift or vibrate loose, potentially causing damage to surrounding parts or creating an unsafe operating condition.
