Husqvarna 586255901 Blade Shaft Bolt LH 5/8-11 x 4.25 for FS 3500 FS 5000 FS 7000 Concrete Saws

OEM Husqvarna Left Hand Thread Blade Shaft Arbor Bolt

The Husqvarna 586255901 Blade Shaft Bolt is a genuine OEM replacement arbor bolt designed for heavy-duty walk-behind concrete saws including the Husqvarna FS 3500, FS 5000, and FS 7000 series. This left-hand thread (LH) hex head cap screw secures the cutting blade assembly to the blade shaft and is engineered to withstand the extreme vibration and torque loads produced during asphalt and concrete cutting operations.

Using the correct OEM arbor bolt is critical for operator safety, proper blade retention, and preventing costly spindle damage. Inferior aftermarket bolts may stretch, loosen, or fail under load.

Why Replace the Blade Shaft Bolt?

Blade shaft bolts experience repeated heat cycles, shock loading, and vibration during cutting operations. Over time bolts can:

Stretch from repeated torque cycles
Develop thread wear
Corrode from slurry and moisture exposure
Lose proper clamping force
Cause blade wobble or flange wear

Replacing worn arbor hardware during blade changes helps prevent expensive spindle and blade flange damage.

Important Installation Notes

This is a LEFT HAND THREAD bolt
Always inspect blade flanges during replacement
Verify proper torque specifications per Husqvarna service manual
Never use impact tools without confirming correct thread direction
Inspect shaft threads for wear before installation
