The Wacker Neuson is a genuine OEM Toothed Lock Washer designed for the BFS 80, BFS 100, and DFS 90 floor saw series. As a direct factory part, it meets the original engineering specifications and installs exactly as the original, with no guesswork on sizing or seating. This washer is confirmed to fit the BFS 80 gasoline floor saw, the BFS 100 gasoline floor saw, and the DFS 90 powered floor saw. Keeping this small but critical fastening component in good condition is essential to maintaining proper clamping force and blade assembly integrity on your saw.
Key Features
- Genuine OEM Fastening Integrity — Manufactured to the original tooth profile and hardness spec, ensuring consistent locking force under the vibration loads typical of floor saw operation.
- Drop-In Installation — Matches the original washer's bore diameter and outer dimensions exactly, seating correctly against mating fastener and housing surfaces without any fitting adjustment.
- Confirmed Fitment — Verified for the BFS 80, BFS 100, and DFS 90 floor saw models; always cross-reference your machine's model number and parts diagram before ordering.
- Prevents Fastener Back-Out — The toothed profile bites into mating surfaces to resist loosening caused by the constant vibration generated during cutting, helping blade-side assemblies stay torqued and secure.
- Blade Assembly Safety — A worn or missing lock washer in a floor saw's blade or guard mounting can allow fasteners to back out during operation; replacing it on schedule is a straightforward step that keeps the cutting assembly properly secured.
A toothed lock washer is a hardened fastening component installed beneath a bolt or nut to prevent unintended loosening through vibration and dynamic loading. The washer's serrated teeth deform slightly when clamped, creating a mechanical grip against both the fastener head and the mating surface that a standard flat washer cannot provide. In a floor saw application — where sustained engine vibration and cutting reaction forces are constant — a failed or absent lock washer can allow critical fasteners to work loose, compromising blade guard security and overall cutting assembly stability.
