Husqvarna Bar Bolt 544036401 vs Pole Saw Blade Retaining Bolt

These are not competing parts. The Husqvarna 544036401 is a bar bolt for Husqvarna chainsaws, and the Pole Saw Blade Retaining Bolt is a 5/16-inch carriage bolt, lock washer and wing nut set for Fanno, Marvin and Smith 20H pole saw heads. Buy the Husqvarna part if you run a Husqvarna, Jonsered, Craftsman or RedMax chainsaw and need the bar nut that clamps the guide bar. Buy the pole saw set if you have a Fanno, Marvin or Smith 20H head and lost its blade hardware. Neither is a substitute for the other, and owners judge them on fit, not features.

• Choose the Husqvarna Bar Bolt if you need a genuine OEM bar nut for a Husqvarna, Jonsered, Craftsman or RedMax chainsaw.
• Choose the Pole Saw Blade Retaining Bolt if you have a Fanno, Marvin or Smith 20H pole saw head and need the carriage bolt, lock washer and wing nut that hold the blade.
