The Wacker Neuson Oval Head Screw 4x 25 TX20 is a genuine OEM fastener designed for the FUH35/2/42 and FUH70 series forced-air heaters. As a direct-from-manufacturer component, this screw is produced to the same specifications as the original hardware installed on these machines, ensuring a consistent, secure fit every time. Compatible across multiple FUH70 variants — including the FUH70/4/42, FUH70/4/42s, FUH70/6/42s, and FUH70/4/42p CH — this part covers a broad range of heater configurations from a single part number.
Key Features
- OEM Thread and Head Geometry — Manufactured to the exact 4x 25 thread specification and oval head profile of the original, so the screw seats flush and holds torque correctly in its housing.
- TX20 Drive Compatibility — Torx TX20 drive pattern delivers positive bit engagement during installation and removal, reducing cam-out risk in tight assembly areas.
- Broad FUH Series Coverage — A single part number covers the FUH35/2/42 and multiple FUH70 variants, making it a practical stock item for fleets running mixed Wacker Neuson heater configurations.
- Consistent Clamping Force — Correct fastener dimensions maintain proper clamping load on panels and covers, keeping internal components secured against vibration during heater operation.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so the material grade and finish match what was used at the factory assembly stage.
An oval head screw serves as a structural fastener that secures panels, covers, or internal brackets within a machine assembly. The oval head profile sits slightly raised above the surface, distributing clamping load evenly while providing a finished appearance where the fastener is visible. When a screw of this type is missing, stripped, or of the wrong thread pitch, the component it secures can loosen under vibration — leading to rattling, misalignment, or damage to surrounding parts over time. Using the correct OEM specification fastener ensures the joint performs as the original design intended.
