The Wacker Neuson Washer B8.4 Ms Flat is a genuine OEM flat washer designed for RD7 series tandem rollers, DPU reversible vibratory plate compactors, and DPS single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, part number meets the exact material and dimensional standards specified for these machines. This washer fits across a wide range of RD7H and RD7He configurations, as well as DPU 2440H, DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPS3050, and DPS3060 models. Keeping fastener assemblies properly loaded with the correct hardware helps maintain structural integrity and prevents premature wear on mating components.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified brass (Ms) composition, ensuring correct hardness and corrosion resistance for the application.
- Exact Dimensional Match — B8.4 sizing seats flush against mating fastener surfaces for even load distribution with no shimming or adaptation needed.
- Broad Model Coverage — A single part number covers RD7H and RD7He tandem rollers, DPU reversible vibratory plates, and DPS single-direction vibratory plates across multiple machine numbers.
- Protects Fastened Joints — A correctly spec'd flat washer distributes clamping force evenly; using an undersized or incorrect washer can allow fasteners to loosen under vibration-heavy operation.
- Direct OEM Sourced — Supplied under Wacker Neuson part number 5000012645, eliminating guesswork when matching hardware to your machine's service documentation.
A flat washer serves as a load-distributing interface between a fastener — bolt head or nut — and the surface it clamps. By spreading clamping force across a wider area, it prevents the fastener from pulling through or damaging softer mating surfaces and helps the joint maintain consistent tension. In high-vibration equipment such as vibratory plate compactors and tandem rollers, fasteners are subjected to constant dynamic loading, making correct washer specification especially important. When a washer is worn, missing, or incorrectly sized, fastener joints can loosen progressively, leading to misalignment, accelerated wear, or component failure in assemblies that depend on a secure, stable connection.
