Key Features

  • OEM-Specified 15/16 Drive Size — Manufactured to Husqvarna's exact dimensional specification for the bladeshaft nut, so the wrench seats fully without slippage or rounding.
  • Purpose-Built for Blade Changes — Engineered specifically for bladeshaft service on Husqvarna floor saws, providing the correct engagement and torque transfer needed for safe blade removal and installation.
  • Broad Floor Saw Compatibility — Fits the FS4800D, FS6600D, FS6800D, FS8400D, Pro65G, and RS8500D floor saws, covering a wide range of Husqvarna's professional walk-behind flat saw lineup.
  • Correct Tool, Correct Outcome — Using the right wrench protects the bladeshaft nut from damage and reduces the risk of over- or under-tightening, which can lead to blade movement or costly shaft repairs.
  • Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, this wrench meets the same standards as the tool originally supplied with the machine.

The bladeshaft wrench is the dedicated service tool used to loosen and torque the nut that secures the diamond blade to the floor saw's blade shaft. Because the shaft nut is tightened to a specific torque value and often under significant load from cutting, using an improperly sized or generic wrench risks damaging the nut or shaft threads, making future blade changes difficult or unsafe. Having the correct OEM wrench on hand ensures every blade swap is performed cleanly and without compromising the integrity of the bladeshaft assembly.
