The Wacker Neuson Lock Nut is a genuine OEM component designed for the BFS series floor saws, including the BFS 1345B, BFS 130RM, BFS 130R, BFS18D, BFS 1350L, BFSX 130RM, and BFSX 130R. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original hardware installed at the factory, ensuring a correct, confident fit every time. This Lock Nut is a critical fastening component that keeps your floor saw operating safely and within spec across demanding cutting applications.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to exact Wacker Neuson thread pitch and hardness specifications, so the locking function performs the way it was engineered to from day one.
- Direct Drop-In Replacement — Matches the original mounting interface on BFS series floor saws; installs in the same position and orientation as the factory-fitted hardware without any adaptation.
- Broad BFS Series Coverage — Fits a wide range of Wacker Neuson floor saw models including the BFS 1345B, BFS 130RM, BFS 130R, BFS18D, BFS 1350L, BFSX 130RM, and BFSX 130R.
- Sustained Clamping Force Under Vibration — The locking design resists loosening during high-vibration cutting cycles, maintaining secure assembly integrity throughout heavy-duty use.
- Blade and Drivetrain Safety — A secure, correctly torqued lock nut is essential on floor saws where blade retention and drivetrain integrity directly affect operator safety; using the correct OEM part ensures the fastener meets the required load rating for these critical connections.
A lock nut is a hardened fastener with a built-in locking mechanism — typically a nylon insert, prevailing-torque thread, or deformed thread section — that prevents the nut from vibrating loose during operation. On a floor saw, components like the blade arbor, drive pulleys, and chassis assemblies are subjected to constant high-frequency vibration and load cycling, which can cause standard nuts to back off over time. When a lock nut fails or is missing, fastener joints can loosen progressively, leading to misalignment, component damage, or unsafe operating conditions. Replacing a worn or missing lock nut with the correct OEM part restores the designed clamping force and keeps critical assemblies securely fastened.
