The Wacker Neuson 4mm Locking Washer is a genuine OEM fastener component designed for a wide range of Wacker Neuson equipment, including the RSS800A single-drum walk-behind roller, BFS 2020AS floor saw, and WB16 series power buggies. As a factory-sourced part, the is manufactured to the exact dimensions and material grade specified for these machines, ensuring a direct drop-in fit with no sizing or compatibility guesswork. This small but critical hardware item is a common service replacement needed during maintenance, repair, or reassembly work across multiple Wacker Neuson product families.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 4mm bore diameter and thickness spec called out in Wacker Neuson's parts documentation, so the washer seats and locks as intended.
- Genuine Locking Design — The locking profile resists loosening under vibration — critical on compaction and saw equipment where constant machine movement would quickly back off a standard flat washer.
- Broad Multi-Machine Fitment — A single part number covers the RSS800A single-drum roller, BFS 2020AS floor saw, GS12Ai portable generator, and the full WB16 power buggy series, making it a practical stocking item for mixed fleets.
- Genuine OEM Sourcing — Supplied directly from Wacker Neuson's parts network, confirming correct material grade and surface treatment for the fastener applications these machines require.
- Common Service Item — Hardware like this locking washer is routinely replaced during teardowns and reassembly; having the correct OEM part on hand keeps service work moving without waiting on sizing substitutes.
A locking washer is a thin fastener placed beneath a bolt or nut to prevent the fastener from backing out due to vibration or dynamic load. On equipment like vibratory rollers, floor saws, and power buggies, mechanical vibration is constant during operation, and a standard flat washer provides no resistance to loosening. The locking washer's spring action or serrated profile bites into both the fastener and the mating surface, maintaining clamp load throughout operation. When a locking washer is missing, worn flat, or substituted with an incorrect size, fasteners can work loose over time, leading to component misalignment, accelerated wear on surrounding parts, or potential structural failure at the joint.
