Key Features
- Genuine OEM Material Spec — Sourced directly from Wacker Neuson, this washer screw meets the exact dimensional tolerances and hardness ratings required for secure fastening in a high-vibration roller environment.
- Correct Thread and Bearing Surface Dimensions — The 5X16 sizing matches the original hardware specification precisely, seating flush and engaging threads as intended without shimming or adaptation.
- Confirmed Fitment for RD11 Series Rollers — Verified for the RD11AEC and RD11A hydrostatic double drum vibratory rollers, two of Wacker Neuson's core walk-behind tandem asphalt and soil compaction machines.
- Maintains Clamping Integrity Under Sustained Vibration — A worn or undersized washer screw can allow fastened assemblies to work loose during drum operation, leading to component shift and accelerated wear on adjacent parts.
A washer screw combines the load-distributing function of a washer with the clamping function of a fastener in a single integrated piece. In a vibratory roller like the RD11A and RD11AEC, where continuous drum oscillation creates constant mechanical stress across the machine's frame and sub-assemblies, correct hardware specification is critical — an ill-fitting or incorrect screw washer can allow joints to loosen over time, compromising structural integrity and the performance of the components it secures. Replacing worn or damaged hardware with the correct OEM part restores the intended clamping load and keeps assemblies performing as designed.
