Wacker Neuson 5000163946 Screw M8X25 Button Head Black Zinc 10.9

The Wacker Neuson is a genuine OEM Screw M8X25 Button Head Black Zinc 10.9 designed for a wide range of Wacker Neuson tandem rollers, ride-on concrete trowels, and compaction rollers. As a factory-sourced fastener, this screw matches the exact grade, coating, and dimensional specification used during original assembly of RD12, RD16, RD27, CRT60, and CB14B series machines. Sourced directly through the Wacker Neuson parts network, the delivers the consistency and traceability that professional operators and fleet maintenance crews depend on. Confirm your machine model before ordering to ensure correct fitment across this broad equipment range.

Key Features

• Grade 10.9 Tensile Strength — High-strength metric fastener rated to 10.9 property class, providing the clamping force needed for structural and mechanical connections in heavy compaction and paving equipment.
• Black Zinc Corrosion Resistance — Black zinc electroplating guards against rust and oxidation in the wet, abrasive environments common to roller and compaction operations.
• Button Head Profile — Low-profile button head sits flush in recessed mounting locations, preventing interference with adjacent components and mating surfaces during reassembly.
• Genuine OEM Sourcing — Manufactured to Wacker Neuson's original material and dimensional specification, ensuring the correct thread pitch, shank length, and head geometry every time.
• Broad Cross-Family Fitment — Verified for use across RD12, RD12A, RD16, RD27, CRT60, and CB14B series machines, covering both tandem rollers and ride-on concrete trowels in a single part number.

A button head cap screw like the Wacker Neuson 5000163946 serves as a structural fastener, securing panels, guards, brackets, and mechanical assemblies to the machine frame. The 10.9 grade rating means the screw is engineered to withstand high clamp loads without yielding, which is critical in high-vibration equipment such as tandem rollers where loosening or fastener failure can lead to component shift or damage. A worn, stripped, or incorrect-grade replacement screw can compromise joint integrity, accelerate wear on mating threads, and create safety hazards during machine operation.
