The Wacker Neuson is a genuine OEM Washer Screw (5X12) designed for a wide range of Wacker Neuson tandem rollers, portable generators, and floor saws. As a direct factory replacement, this fastener hardware component ensures a correct, secure fit across the full range of compatible machines it was engineered for. Confirmed fitment includes the RD12A-90 and RD11A tandem roller series, GP3800A, GP5600A, GP6600A, GPS5600A, GPS6600A, GV3800A, GV5600A, GV6600A portable generator families, and the BFS 2020AS floor saw.
Key Features
- Genuine OEM Hardware Spec: — Manufactured to Wacker Neuson's exact thread pitch and head geometry for the 5X12 washer screw profile, ensuring correct clamping force and seating across all listed assemblies.
- Drop-In Replacement: — Installs directly into existing mounting points with no rework needed; matches the original fastener's dimensions for immediate reassembly.
- Broad Multi-Platform Fitment: — Covers the RD12A-90 and RD11A tandem roller series, the full GP/GPS/GV 3800–6600 generator range, and the BFS 2020AS floor saw in a single part number.
- Structural Integrity Where It Counts: — A correctly sized and torqued washer screw distributes clamping load evenly across the mating surface, preventing panel vibration, loosening, or component shift under load.
- Genuine Part Traceability: — Sourced directly through Wacker Neuson's OEM supply chain, so you receive the correct grade and finish specified for these machines at the time of manufacture.
A washer screw combines a machine screw and an integrated washer flange into a single fastener, spreading the clamping load over a broader surface area than a standard screw alone. This prevents the fastener from pulling through or deforming thinner panels and brackets — a common concern on equipment subject to sustained vibration, such as compaction rollers and generator frames. When a washer screw of the wrong size or grade is used, it can work loose under vibration, leading to rattling covers, misaligned components, or more serious mechanical faults over time.
