The Wacker Neuson Screw is a genuine OEM fastener designed for the HI200D, HI200HD D, HI300D, HI300HD D, HI400HD G, and HI400HD D series indirect air heaters. As a direct factory replacement, this screw matches the original specification for thread form, head geometry, and material grade — ensuring correct installation without guesswork. It is confirmed compatible across multiple HI-series heater configurations, covering both diesel and gas-fired units in the HI200, HI300, and HI400 families.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original thread and material specification, so it seats and torques exactly as the factory intended — no stripped threads or fitment compromises.
- Drop-In Replacement — Matches the original fastener's head type and thread profile for straightforward installation using standard tooling.
- Broad HI-Series Compatibility — Fits HI200D, HI200HD D, HI300D, HI300HD D, HI400HD G, and HI400HD D indirect air heaters, covering both diesel and gas-fired configurations across the HI200, HI300, and HI400 families.
- Structural Integrity Maintained — A correctly spec'd fastener keeps heater panels, housings, and assemblies securely fastened under the thermal cycling and vibration typical of construction site operation.
- Verified Part Number — Order with confidence: part number 5200011949 is the current Wacker Neuson OEM reference for this application across all listed HI-series models.
Screws in indirect air heater assemblies secure panels, covers, and internal components that must remain firmly in place during operation. Thermal expansion and vibration on active job sites can cause worn or incorrect fasteners to loosen over time, leading to misaligned covers, air leaks, or rattling components that affect heater performance. Using the correct OEM-spec screw — with the right thread engagement and material grade — ensures the assembly stays tight and functions as designed throughout the heating season.
