The Wacker Neuson Screw with Washer is a genuine OEM fastener assembly designed for the PT4A and PT4A(I) series trash pumps. Sourced directly through Wacker Neuson's authorized parts program, this hardware assembly meets the original design specifications for the machines it serves. It is confirmed to fit multiple PT4A configurations, including those built under model numbers, and, giving you confidence you're ordering the right part the first time.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to the original thread pitch, head dimensions, and washer profile specified for the PT4A platform — no guesswork on fit or torque compatibility.
- Integrated Washer Design — The captive washer stays in place during installation, making single-handed fastening in tight pump housings straightforward and consistent.
- Verified PT4A and PT4A(I) Compatibility — Confirmed fitment across PT4A and PT4A(I) series trash pumps, covering a range of production configurations within that model family.
- Correct Clamping Force — A properly sized screw and washer assembly distributes load evenly across the mating surface, preventing panel distortion, fastener loosening from vibration, and potential housing damage over extended pump operation.
- Direct OEM Reference — Part number 5100044585 cross-references directly to the Wacker Neuson parts catalog, making it straightforward to verify against your machine's service documentation.
A screw with washer assembly serves as a primary fastening component that secures panels, covers, or internal assemblies within the pump housing. The integrated washer distributes the clamping load across a wider surface area, protecting the material being fastened from damage and helping the fastener resist loosening under continuous vibration — a condition common in engine-driven pump applications. When a screw strips, corrodes, or goes missing, it can compromise the integrity of whatever component it holds in place, leading to misalignment, leaks, or accelerated wear on surrounding parts.
