The Wacker Neuson Lock Washer 3/8 Split is a genuine OEM fastening component designed for the BFS 2020AS and BFS 1318AS self-propelled walk-behind floor saws. As a direct factory replacement, this washer meets the original engineering specifications and installs exactly as the factory-fitted part. Whether you are completing a scheduled service or replacing a worn fastener, part number keeps your saw's hardware properly torqued and secured. Wacker Neuson's genuine OEM designation confirms this washer is sourced from the same supply chain as the original production component.
Key Features
- Genuine OEM Fastener Integrity — Split-lock design provides the correct spring tension and bite angle specified for Wacker Neuson floor saw assemblies, maintaining clamp load under vibration.
- Direct Hardware Match — 3/8 split configuration seats flush against mating surfaces in the BFS series, allowing straightforward bolt-up without shimming or modification.
- Confirmed Fitment — Verified for the BFS 2020AS and BFS 1318AS self-propelled walk-behind floor saws.
- Vibration Resistance — The split-lock profile bites into the fastener and mating surface to resist loosening under the constant vibration generated during concrete and asphalt cutting operations.
- Blade and Guard Assembly Security — A failed or absent lock washer can allow critical fasteners to back out during cutting, making correct hardware a genuine operational safety consideration on rotating-blade equipment.
A lock washer is a thin, slotted ring placed beneath a bolt or nut to prevent fastener loosening caused by vibration and dynamic loading. On a walk-behind floor saw like the BFS series, the machine's cutting action generates sustained vibration that can gradually back out standard fasteners over time. The split-lock design works by acting as a spring — as the nut or bolt is torqued down, the washer's open ends bite into both the fastener face and the mounting surface, creating resistance against rotation. When a lock washer is missing, worn flat, or incorrectly sized, fasteners can work loose during operation, leading to misaligned components, accelerated wear, and potential safety hazards on a machine running a high-speed cutting blade.
