Key Features
- Genuine OEM Hardware Grade — Manufactured to Husqvarna's exact thread pitch, dimensional tolerances, and material specification, ensuring the nut seats and torques correctly every time.
- Direct Drop-In Replacement — Matches the original fastener specification exactly; cross-reference part number 731231601 against your machine's parts diagram to confirm the correct installation point.
- Broad Equipment Compatibility — Fits across multiple Husqvarna construction equipment families, including FS-series floor saws, PG and HTC floor grinders, PP power packs, K-series power cutters, TS tile and masonry saws, and Blastrac shot blasters.
- Structural Integrity Restored — A correctly specified nut maintains proper clamping force at critical assembly joints; an incorrect or worn fastener can lead to loosening, misalignment, or component damage under operating loads.
- Wide-Application OEM Part — Used across a broad range of assemblies on many machines, making this a practical part to source when completing multi-point service or assembly work on Husqvarna construction equipment.
A hexagon nut is a standard threaded fastener used to secure components at assembly joints throughout the machine. It works in combination with a bolt or stud to clamp parts together and maintain structural integrity under the vibration and load stresses typical of construction equipment operation. When the wrong nut is used — or when a nut is damaged, stripped, or missing — the assembly joint can lose clamping force, leading to movement, wear, or failure of the connected components. Using the correct OEM-specified nut ensures the joint performs as designed across the full service life of the machine.
