The Wacker Neuson Screw is a genuine OEM fastener designed for PT3A, PT4A, PT3A(I), and PT4A(I) series self-priming centrifugal trash pumps, as well as the GP3800A portable generator. Sourced directly from Wacker Neuson, this screw matches the original component specification to ensure a correct, stable installation without guesswork. Fitment extends across multiple pump and generator configurations in these model families, making it a versatile service item to have on hand. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's original threading and dimensional spec, so torque loads and clamping forces behave exactly as designed for pump and generator housings.
- Drop-In Installation — Matches the original hole pattern and thread pitch of the mating component, so it seats cleanly without reworking the mount point.
- Broad Model Coverage — Fits PT3A, PT4A, PT3A(I), and PT4A(I) trash pumps across multiple serial configurations, plus the GP3800A portable generator.
- Structural Consistency Under Load — A correctly torqued fastener holds critical pump and generator panels, covers, or brackets secure during high-vibration operation; a stripped or missing screw can allow covers to shift and expose internal components.
- Traceability You Can Trust — Part number 5200000501 is the active Wacker Neuson OEM reference, so you can cross-check against your parts manual with confidence.
A screw may seem like a minor component, but fasteners in pump and generator assemblies carry real structural responsibility — they secure housings, panels, and covers that protect internal mechanical and electrical systems from debris, moisture, and vibration damage. When a screw is missing, stripped, or replaced with an incorrect substitute, the joint can loosen over time, allowing covers to rattle free or creating misalignment in the assembled unit. Using the correct OEM fastener with the right thread form and material grade ensures the joint holds to specification throughout the service life of the machine.
