Wacker Neuson 5000155842 Screw M6X20 Hex Head Serrated Flange Black

The Wacker Neuson is a genuine OEM Screw M6X20 Hex Head Serrated Flange Black designed for the RD7H-ES and RD7H-S tandem roller series. As a factory-sourced fastener, part is manufactured to the exact dimensions and material specifications of the original hardware installed on these machines. It fits the RD7H-ES and RD7H-S models, including both EU-configured variants and standard domestic configurations. When hardware wears, loosens, or strips, replacing it with the correct OEM screw ensures panels, guards, and assemblies seat and torque the way Wacker Neuson designed them to.

Key Features

• Serrated Flange Locking Action — The integrated serrated flange bites into the mating surface to resist vibration-induced loosening, which is critical on compaction equipment subject to continuous dynamic load.
• Correct M6X20 Thread and Length — Matches the original fastener specification exactly, threading directly into existing bosses and tapped holes without rework or thread chasing.
• Black Oxide Finish — The black coating provides a base layer of corrosion resistance suited to the outdoor and all-weather operating environment of walk-behind tandem rollers.
• Genuine OEM Sourcing — Sourced directly through Wacker Neuson, this screw is the same part number specified in the OEM parts diagram for the RD7H-ES and RD7H-S roller families.
• Broad RD7 Series Coverage — Confirmed fit across the RD7H-ES EU, RD7H-S EU, RD7H-ES, and RD7H-S tandem roller configurations.

A hex head serrated flange screw is a fastener that combines a standard hex drive head with a flange bearing surface ringed with small serrations. On a walk-behind tandem roller like the RD7, the machine transmits significant vibration through the frame during operation — vibration that can work standard fasteners loose over time. The serrated flange digs into the substrate with each tightening pass and maintains clamp load even as the machine cycles through compaction passes. A missing or damaged screw can allow covers, deflectors, or structural panels to shift, creating both an operational hazard and the potential for secondary damage to underlying components.
