Husqvarna 530015793 Left-hand Flange Nut

Product Description

The HUSQVARNA 530015793 is a left-hand threaded flange nut designed as a direct OEM replacement fastener for Husqvarna outdoor power equipment. Left-hand thread means the nut tightens counterclockwise and loosens clockwise, a design used on rotating assemblies where standard right-hand threads would back off under normal blade or arbor rotation. This part is used by technicians and equipment service professionals performing cutting deck, blade, or arbor maintenance on compatible Husqvarna lawn and garden equipment.

This flange nut is intended for use in Husqvarna lawn and garden applications where a left-hand threaded fastener is required to secure a rotating component. The integrated flange distributes clamping load across a wider surface area, reducing the risk of fastener loosening under vibration and dynamic loads typical of outdoor power equipment operation. Service technicians working on mowing or cutting system components will encounter this fastener type on affected spindle or blade arbor assemblies.

Key Features

• Left-hand thread prevents self-loosening on counterclockwise-rotating arbor and blade assemblies
• Integrated flange provides wider load distribution compared to a standard hex nut
• OEM Husqvarna part number ensures correct thread pitch and dimensional fit
• Designed for lawn and garden outdoor power equipment applications

Compatibility

Designed as an OEM replacement flange nut for Husqvarna lawn and garden power equipment requiring a left-hand threaded fastener at the blade arbor or rotating assembly.

Installation Notes

Installation and removal of this part should be performed by a qualified small-engine or outdoor-power-equipment technician. Disconnect the spark plug wire and ensure the engine is fully stopped before servicing any blade or spindle assembly. Use an appropriate blade-holding tool to prevent rotation while torquing the nut. Because this is a left-hand thread, apply counterclockwise rotation to tighten and clockwise rotation to loosen.
