As a genuine OEM component, it is manufactured to Husqvarna's exact dimensional and material specifications, ensuring consistent clamping force and thread engagement wherever it is installed. Cross-reference part number 732251801 against your parts diagram to confirm the correct application before ordering. DHS Equipment supplies this part to help keep your equipment running at full capacity.

Key Features

• Genuine OEM Thread Specification — Manufactured to Husqvarna's exact thread pitch, width-across-flats, and hardness grade, so torque values and clamping loads remain within design limits.
• Locking Design Integrity — The prevailing-torque locking feature resists loosening under vibration, making this nut well suited to the high-cycle, high-vibration environments of saws, trowels, grinders, and drill motors.
• Broad Cross-Platform Fitment — A single part number covers CT36 and CT48 power trowels, multiple FS floor saws, DM and DMS drill motors and systems, PP power packs, PG and HTC floor grinders, DC dust collectors, and CS wire saws — confirm your model against part number 732251801 before installing.
• Correct Material Grade — OEM-sourced steel construction provides the tensile strength required for structural and assembly fastening points throughout Husqvarna's construction equipment lineup.
• Direct Drop-In Replacement — Matches the original fastener's dimensions exactly, so reassembly proceeds without modification to surrounding hardware or mating components.

A hexagon locking nut is a critical fastening component that secures assemblies and retains mechanical connections under load. Unlike a standard hex nut, the locking variant incorporates a prevailing-torque element — typically a distorted thread section or nylon insert — that resists self-loosening caused by vibration, thermal cycling, and dynamic loads. When a locking nut loses its holding force or is replaced with a non-locking fastener of the wrong specification, assemblies can shift, develop play, or come apart during operation, leading to accelerated wear of surrounding components and potential equipment damage. Using the correct OEM replacement maintains the clamping integrity the original design depends on.
