The Wacker Neuson Hexagonal Flange Head Screw is a genuine OEM component designed for the APT4S and APT4T pump series. Sourced directly from Wacker Neuson, this screw matches the exact specifications of the original hardware used during factory assembly, ensuring a correct, secure installation every time. It is compatible across multiple APT4S and APT4T configurations, including surge brake, electric brake, and cold weather variants.
Key Features
- OEM-Matched Thread and Flange Geometry — Manufactured to the same dimensional tolerances as the original, so the integrated flange seats flush and distributes clamping load correctly without deforming mounting surfaces.
- Drop-In Hardware Replacement — Replaces the original screw position-for-position with no rework to surrounding components or fastener holes required.
- Broad APT Series Coverage — Fits APT4S Pump with Skid and APT4T Pump configurations, including surge brake, electric brake, and cold weather variants across both model lines.
- Secure Fastening Under Pump Vibration — The flanged head design resists loosening during pump operation, maintaining joint integrity and preventing component shift or fluid pathway misalignment.
- Genuine Wacker Neuson Part — Carries the full confidence of an authorized OEM replacement, verified against part number 5200019882 for accurate fitment on supported models.
A hexagonal flange head screw combines a standard hex bolt head with a wide, integrated flange that acts as a built-in washer. This design spreads the clamping force over a larger surface area, reducing the risk of loosening under vibration and preventing surface damage to the components being fastened. When this type of fastener wears, corrodes, or is stripped, it can compromise the structural integrity of the assembly it holds together, leading to misalignment, leaks, or component failure in service.
