The Wacker Neuson is a genuine OEM Washer #10 Split Lock designed for the BFS 2020AS and BFS 1318AS series floor saws. Sourced directly from Wacker Neuson, this fastener hardware carries the same specifications as the original component installed at the factory. Confirmed fitment covers the BFS 2020AS walk-behind saw and the BFS 1318AS self-propelled walk-behind saw, making a direct service replacement for both machines.
Key Features
- Genuine OEM Specification: — Manufactured to the exact hardness and split-profile tolerances required for secure torque retention in floor saw fastener applications.
- Drop-In Hardware Replacement: — Sized and profiled to seat correctly against mating fasteners and surfaces on BFS series floor saws without any reworking of surrounding hardware.
- Confirmed BFS Saw Compatibility: — Verified fitment for the BFS 2020AS and BFS 1318AS walk-behind floor saws; cross-reference part number 5000163778 before ordering.
- Vibration-Resistant Locking Action: — The split-lock design bites into mating surfaces under load, resisting loosening caused by the constant vibration generated during concrete and asphalt cutting.
- Safety-Critical Fastener Integrity: — On a high-speed cutting machine, a loose or failed lock washer can allow blade guards, covers, or structural fasteners to back out during operation; replacing worn hardware maintains secure assembly.
A split lock washer is a thin, helically formed ring placed beneath a bolt or nut to prevent fastener loosening under vibration and dynamic loads. As the fastener is tightened, the split ends of the washer bite into both the fastener face and the mating surface, creating a mechanical resistance to rotation. On floor saws like the BFS 2020AS and BFS 1318AS — machines that transmit significant vibration through the frame during cutting — maintaining proper fastener tension is essential to keeping components secured and aligned. A worn, flattened, or missing lock washer allows fasteners to gradually back out, which can lead to component misalignment, structural loosening, or unsafe operating conditions.
