Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional and material specifications, ensuring the Key seats and functions correctly within the FS309 drivetrain or ignition assembly.
- Exact-Match Replacement — Engineered to drop directly into the original mounting position with no modification to surrounding components required.
- FS309 Floor Saw Compatibility — Verified fitment for the Husqvarna FS309 floor saw, so you can order with confidence knowing this is the correct part for your machine.
- Restored Mechanical Engagement — A worn or missing key can cause shaft slippage, loss of drive engagement, or ignition failure; replacing it with this OEM component restores proper mechanical connection and machine function.
- Correct Torque Transfer — Keys are precision-sized to fill the keyway without play, ensuring full torque is transmitted between mating components without stress concentration or premature wear.
A key is a small but critical mechanical component that locks a rotating shaft to a gear, pulley, or blade hub, preventing slippage between the two mating parts during operation. When a key shears or wears, the shaft and its driven component can rotate independently, resulting in lost drive power or complete loss of function in that assembly. Replacing a damaged key promptly restores the positive mechanical connection that the machine depends on for consistent, controlled operation.
