The Wacker Neuson M14 Hex Nut is a genuine OEM fastener designed for the BFS and MFS series floor saws, including the BFS12, BFS16, BFS18, BFS20, BFSX, MFS12, and MFS14 model lines. As a direct factory-sourced component, this nut is manufactured to the exact thread pitch, hardness, and dimensional tolerances specified for these machines. Whether you are servicing a BFS18D, a BFSX20D, or any of the covered BFS 614 and BFSX models, part number ensures a correct, rattle-free fit without the guesswork of sourcing a generic substitute. Keep a spare on hand — small fasteners like this are often the first thing needed to get a saw back in service quickly.
Key Features
- OEM Thread and Hardness Rating — Manufactured to Wacker Neuson's specified M14 thread standard and material grade, so clamping force is consistent and reliable under the vibration loads typical of floor saw operation.
- Drop-In Installation — Matches the original fastener geometry exactly, threading directly onto existing studs and bolts without chasing threads or sourcing additional hardware.
- Wide BFS and MFS Series Coverage — Confirmed fitment across BFS12, BFS16, BFS18, BFS20, BFSX, MFS12, and MFS14 model families, covering both standard and D-suffix (direct drive) variants.
- Holds Critical Assemblies Secure — A correctly torqued M14 hex nut maintains the integrity of blade guards, frames, and drive components; a worn or missing nut can allow assemblies to shift under load, affecting cut accuracy and operator control.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, so you receive the same fastener installed at the factory — not an unverified substitute with unknown material specs.
An M14 hex nut is a standard metric fastening component used to secure bolted joints throughout the floor saw's frame, blade guard assembly, and drive system. Its role is to apply and maintain the correct clamping force that holds two or more components together under the constant vibration generated during concrete or asphalt cutting. When a hex nut becomes stripped, corroded, or lost, the joint it secures can loosen progressively, leading to misalignment, increased wear on adjacent components, or an unsafe working condition. Replacing a damaged or missing nut promptly with the correct OEM part keeps the assembly properly torqued and the machine operating as intended.
