Wacker Neuson 5000038140 Hexagon Cap Nut

The Wacker Neuson is a genuine OEM Hexagon Cap Nut designed for PT2 series self-priming centrifugal trash pumps and compatible FUE and KTU converter units. As a direct OEM replacement, this fastener is manufactured to the same specification as the original hardware installed at the factory, ensuring a correct, secure fit without any guesswork. Verified fitment covers the PT2Y, PT2A, PT2B, and PT2R pump models, as well as a range of FUE and KTU converter configurations. Keeping the correct fastener hardware on hand means faster service turnarounds and confidence that critical assemblies are properly secured.

Key Features

• OEM-Grade Fastener Material — Manufactured to Wacker Neuson's original torque and thread specification, ensuring the nut seats and clamps correctly without stripping or deforming under operational loads.
• Direct Drop-In Installation — Matches the original hex drive size and thread pitch, so it installs with standard wrenches and mates directly to the existing threaded hardware on the pump or converter assembly.
• Broad PT2 Series and Converter Compatibility — Confirmed fit across PT2Y, PT2A, PT2B, and PT2R trash pump models, plus FUE and KTU converter units including FUE 2/042/200W, FUE 1/042/200W, KTU 2/250/200W, and related variants.
• Maintains Clamping Integrity — A correctly torqued cap nut keeps covers, housings, and fluid-circuit connections sealed under pump vibration and pressure. A worn or missing nut risks loosening of critical assemblies and potential leaks.
• Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network and carries part number 5000038140 for straightforward cross-referencing against your machine's parts diagram.

A hexagon cap nut is a closed-end fastener used to secure components while simultaneously capping and protecting the exposed end of the bolt or stud thread it covers. On trash pumps and converter assemblies, these nuts are commonly used where vibration resistance and thread protection are both required — the closed cap prevents debris, moisture, and corrosive fluids from compromising the thread engagement. When a cap nut becomes damaged, corroded, or lost, the exposed threads beneath are vulnerable to damage and the clamping force on the assembly is reduced, which can allow covers or housings to work loose during operation.
