The Wacker Neuson Screw is a genuine OEM screw designed for the PT3A, PT4A, PT3A(I), and PT4A(I) series trash pumps. Sourced directly from Wacker Neuson, this screw meets the exact material and dimensional standards used in original production, so it seats and torques correctly the first time. It covers the full PT3A and PT4A lineup — including both standard and I-series models — making it the straightforward choice when you need a verified, like-for-like replacement.
Key Features
- Genuine OEM Material Grade — Manufactured to the same hardness and thread specification as the original production screw, ensuring correct torque retention without stripping or seizing.
- Direct Thread-for-Thread Replacement — Matches the original thread pitch and head pattern exactly, so it installs into existing mounting points without chasing threads or sourcing adaptors.
- Broad PT-Series Fitment — Confirmed for PT3A, PT4A, PT3A(I), and PT4A(I) trash pumps across multiple production variants, covering a wide share of Wacker Neuson's portable pump fleet.
- Secure Fastening Under Vibration — A correctly spec'd OEM screw maintains clamping force during the continuous vibration typical of trash pump operation, preventing loosening that can lead to misaligned components or leaks.
- Verified by Part Number 5100044494 — Cross-reference against your pump's parts diagram using part number 5100044494 to confirm fitment before ordering.
A screw may be one of the smallest components in a trash pump assembly, but its role is foundational — it holds panels, guards, brackets, and mechanical assemblies in precise alignment under constant load and vibration. When a screw is damaged, corroded, or missing, the components it secures can shift or come loose, leading to accelerated wear on surrounding parts or an outright stoppage. Using the correct OEM-spec screw ensures the joint holds to the designed clamping force and that adjacent components stay true throughout the pump's working life.
