The Husqvarna 725633051 Screw MF6S 5x16 10.9 is a genuine OEM fastener designed for Husqvarna wall saws, including the WS440HF, WS400, WS440, WS462, WS482, and WS8. As a factory-original component, this screw is manufactured to the exact grade and dimensional specification Husqvarna engineers intended, ensuring a secure, properly torqued connection wherever it is applied. DHS Equipment supplies this part to help keep your wall saw operating at full capacity.
Key Features
- Grade 10.9 High-Tensile Construction — manufactured to a 10.9 property class rating, delivering the clamping force and shear resistance required for structural fastener applications in demanding wall saw assemblies.
- Exact OEM Dimensional Specification — the M5 x 16 mm thread and head profile match the original factory fastener exactly, seating flush and threading correctly without rework or adjustment.
- Broad Wall Saw Compatibility — fits the WS440HF, WS400, WS440, WS462, WS482, and WS8 wall saws, covering the full range of Husqvarna track-mounted wall saw models.
- Genuine Husqvarna OEM Part — sourced directly through the Husqvarna OEM supply chain, so the material grade, thread pitch, and surface treatment are verified against the original engineering specification.
- Structural Integrity Where It Counts — a correctly rated fastener maintains the rigid connection between wall saw components; substituting an under-rated or incorrect-length screw risks loosening, component shift, or joint failure under load.
A high-tensile fastener like this screw is a critical structural element in wall saw assemblies, where vibration, cutting loads, and repeated repositioning place sustained stress on every joint. The 10.9 grade designation indicates the screw meets a specific proof load and tensile strength standard, making it suitable for applications where fastener failure could compromise the alignment or stability of the cutting system. Using the correct OEM-specified fastener — cross-reference 725633051 against your parts diagram to confirm the exact position — ensures the joint is torqued and retained as the machine was designed to operate.
