The Wacker Neuson 5200019830 Bolt is a genuine OEM fastener designed for APT4T and APT4S series self-priming pumps. As a direct OEM replacement, it is manufactured to the same specifications as the original hardware installed at the factory, ensuring a consistent, secure connection wherever it is used in the assembly. This bolt is confirmed to fit multiple APT4T and APT4S configurations, including surge brake, electric brake, and cold weather variants. Keeping the correct fastener in place is essential to maintaining the structural integrity and safe operation of your pump unit.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact material and dimensional standards of the original bolt, delivering the thread engagement and clamping force the pump assembly requires.
- Direct Drop-In Replacement — Matches the original bolt specification for thread pitch, length, and head type, so installation is straightforward with standard tooling.
- Broad APT4T and APT4S Fitment — Compatible across APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, APT4S Pump with Skid, and their respective Cold Weather variants.
- Structural Integrity Under Load — A correctly torqued fastener keeps critical pump components securely seated during operation; a worn, stripped, or incorrect bolt can cause component shift, leaks, or assembly failure.
- Fastener Safety in Pump Applications — In pump assemblies subject to vibration and hydraulic forces, using the correct OEM-spec bolt prevents loosening and maintains safe containment of fluid-side components.
A bolt may be one of the smallest components in a pump assembly, but it plays a direct role in holding structural and functional elements firmly in position during operation. In self-priming pump units like the APT4T and APT4S, fasteners are exposed to constant vibration, pressure fluctuations, and environmental stress. Using an incorrect or substandard bolt risks under-clamping, thread stripping, or gradual loosening — any of which can lead to misalignment, fluid leaks, or component damage. Replacing with the correct OEM part ensures the joint performs as originally engineered.
