The Wacker Neuson Screw M4 x 25 Machine Pan Head is a genuine OEM fastener designed for the ML440, ML240, ML425, and ML225 Light Tower series, as well as ML440 and ML240 Multifunction Floodlight Towers and PT6Y and PT6YT series power trowels. As a direct Wacker Neuson OEM part, the ships to spec — correct thread pitch, head profile, and material grade — so it seats exactly as the original did. This fastener covers a broad range of Wacker Neuson light tower and power trowel configurations, making it a practical stock item for crews running multiple units on site.
Key Features
- OEM Thread and Head Accuracy — Manufactured to Wacker Neuson specification with the correct M4 x 25 thread form and pan head profile, ensuring consistent torque and flush seating in the original mounting point.
- Drop-In Fastener Replacement — Matches the original installation hole pattern and drive type, so the screw installs with standard tooling and no rework to the surrounding hardware.
- Broad Model Coverage — Compatible with ML440, ML240, ML425, and ML225 Light Towers, ML-series Multifunction Floodlight Towers, and PT6Y and PT6YT power trowels across multiple configuration codes.
- Structural Integrity Where It Counts — A correctly torqued machine screw keeps panels, covers, and components firmly located; a stripped or missing fastener allows vibration-induced movement that accelerates wear on adjacent parts.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, so the part number, material grade, and dimensions match the original build record exactly.
A machine pan head screw is a threaded fastener used to secure covers, brackets, electrical components, and structural panels to a machine's frame or housing. The pan head profile distributes clamping load across a wider bearing surface than a countersunk head, making it well suited to thinner sheet metal and plastic enclosures common on light tower and power trowel assemblies. When a screw like this shears, strips, or goes missing, the component it holds can shift under vibration, leading to misalignment, accelerated wear on surrounding parts, or exposure of sensitive internals to dust and moisture.
