Husqvarna Nut OEM #505172301

Maintain secure, factory-correct fastener assemblies on your Husqvarna outdoor power equipment with this Genuine OEM Nut (Part #505172301). This genuine Husqvarna part replaces old part numbers 506 60 92-01 and 506 60 98-01 — making it a confirmed factory-authorized cross-reference upgrade manufactured to exact Husqvarna material, thread, and dimensional specifications. Whether securing a cover, housing, shaft component, or structural assembly, this OEM nut delivers the precise thread engagement, clamping force, and material quality required for reliable, long-lasting performance.

Why Genuine OEM Fasteners Matter:
It may seem like any hardware store nut will do the job — but Husqvarna’s OEM fasteners are manufactured to exact thread pitch, diameter, hardness, and torque specifications for each specific application on their equipment. An incorrect or substandard nut can strip threads, fail to achieve proper clamping torque, loosen under vibration, or cause damage to mating components. Using the correct genuine OEM nut ensures the assembly performs exactly as Husqvarna’s engineers designed — maintaining proper clamping force, protecting threads, and keeping critical components securely fastened through demanding operating conditions.

Signs Your Nut Needs Replacement:

• Visible thread stripping, deformation, or corrosion on the nut
• Nut will not achieve or maintain proper torque specification
• Fastener loosening repeatedly under normal vibration and operation
• Rounded hex flats making installation or removal difficult
• Nut damaged, lost, or missing from the assembly
• Routine service, rebuild, or reassembly requiring fresh hardware

Key Features:

• Genuine Husqvarna OEM part — not aftermarket or generic hardware store substitute
• Replaces superseded part numbers 506 60 92-01 and 506 60 98-01 — factory-confirmed upgrade 
• Manufactured to exact Husqvarna thread pitch, diameter, and material hardness specifications

• Resists loosening under the vibration and load cycles of outdoor power equipment operation
• Direct OEM replacement — installs to factory specification without modification

Compatibility:
This OEM nut fits select Husqvarna outdoor power equipment models. Always confirm fitment using your Husqvarna model and serial number — found on a label on the engine housing, equipment frame, or recoil assembly — and cross-reference against your unit’s Illustrated Parts List (IPL) before ordering to verify the correct nut specification for your specific assembly point.
