The Wacker Neuson Hexagonal Flange Head Screw is a genuine OEM component designed for the LTN4Y and LTN5Y light tower series as well as APT4S and APT4T pump models. As a direct factory replacement, this screw is sourced through Wacker Neuson's authorized supply chain, ensuring the correct thread specification, flange geometry, and material grade for every application it covers. It fits across an extensive range of configurations including standard, cold weather, high altitude, and surge or electric brake variants within the LTN and APT4 families. Keep this part on hand for scheduled maintenance or unplanned repairs to stay operational without unnecessary delays.
Key Features
- Correct Thread and Flange Specification — Manufactured to the exact dimensional tolerances of the original, ensuring proper seating and clamp load without over-tightening or stripping risk.
- Genuine OEM Sourcing — Supplied directly through Wacker Neuson's authorized parts network, confirming this is the same screw used in original equipment assembly.
- Broad Model Coverage — Fits LTN4Y and LTN5Y light tower variants (including SA, CH, UK, RH, 60Hz, and 120V/60Hz configurations) plus APT4S and APT4T pump models in standard and cold weather builds.
- Structural Integrity Under Vibration — The integrated flange distributes clamping force evenly, maintaining secure fastening even in high-vibration operating environments typical of generators and pump equipment.
- Verified Part Number Match — Part number 5200019883 is confirmed against Wacker Neuson's official parts documentation, giving you confidence you are ordering the right component the first time.
A hexagonal flange head screw combines a standard hex bolt head with a built-in washer-style flange beneath it, allowing it to distribute clamping load across a wider surface area without a separate washer. This design is commonly used in assemblies where vibration resistance and secure fastening are critical, such as engine mounts, panel enclosures, and mechanical subframes on light towers and water pumps. When a flange head screw loosens, stretches, or fails, the components it secures can shift or become structurally compromised, leading to accelerated wear on surrounding parts or unsafe operating conditions.
