Key Features

• Genuine OEM Flat Washer — Manufactured to Wacker Neuson's dimensional and material specifications for the A4.3 bore size, ensuring correct load distribution and clamping force across every fastener application.
• Direct Hardware Replacement — Matches the original washer's thickness, outer diameter, and bore tolerance so it seats flush against mating fastener hardware without shimming or modification.
• Broad Cross-Equipment Compatibility — A single part number covers RD12 and RD16 tandem rollers, G-Series generators (G25 through G320), BS-series rammers, CRT ride-on trowels, LTW light towers, RT trench rollers, BFS floor saws, and DPU reversible plates — ideal for parts consolidation across a mixed fleet.
• Correct Load Distribution — A properly sized flat washer prevents bolt-head pull-through, protects mating surfaces from damage, and maintains consistent clamp load — all critical on equipment subject to vibration and heavy-duty cycles.
• Authentic Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM parts network, so the part number, dimensions, and material grade match what was installed when the machine was built.

A flat washer serves as a load-spreading interface between a fastener — bolt head or nut — and the surface it bears against. By distributing clamping force over a wider area, it prevents the fastener from embedding into or damaging the substrate and helps maintain a consistent, stable clamp load over time. On equipment that operates under constant vibration, such as compaction machines, generators running under load, and trowels, maintaining proper clamp load is essential; a missing or incorrectly sized washer can allow fasteners to work loose progressively, leading to component misalignment or fastener failure. The Wacker Neuson 5000010628 Washer A4.3 Flat is the correct OEM-specified hardware for the A4.3 bolt clearance diameter used across numerous assembly points throughout these machine families.
