The Wacker Neuson M16 Hex Dome Nut is a genuine OEM fastener designed for the ML440, ML240, ML425, and ML225 Light Tower and Multifunction Floodlight Tower series. Sourced directly from Wacker Neuson, this OEM part delivers the exact thread specification and dome profile required for proper installation and long-term holding strength. It is a verified direct replacement that covers a broad range of ML-series Light Tower configurations, ensuring you get the right part the first time.
Key Features
- OEM Thread Accuracy — Manufactured to the exact M16 thread pitch and torque specification, ensuring the nut seats and clamps correctly without over-tightening risk.
- Dome Profile Integrity — The closed dome cap shields the exposed bolt end from moisture and debris ingress, protecting the fastened joint against corrosion in outdoor light tower environments.
- Direct OEM Replacement — Part number 5000404305 installs hand-to-wrench with no rework, matching the original hex drive dimensions for standard tooling.
- Broad ML-Series Compatibility — Fits ML440, ML240, ML425, and ML225 Light Towers and Multifunction Floodlight Towers across multiple build configurations, covering a wide range of Wacker Neuson tower equipment.
- Structural Holding Performance — A correctly torqued M16 hex dome nut maintains the clamping load on critical tower assemblies; a worn or stripped nut can allow joint loosening and structural movement under vibration.
An M16 hex dome nut — also known as an acorn nut — combines the fastening function of a standard hex nut with a rounded, closed-end cap that covers the exposed thread of a bolt or stud. On light towers and floodlight equipment, these fasteners are typically used in structural and panel mounting locations where the bolt end needs protection from weather exposure. When a dome nut is cracked, stripped, or corroded, it can compromise joint integrity and allow moisture to attack the underlying bolt thread, leading to difficult removal and potential structural loosening over time.
