Compatibility
Compatible with Husqvarna Chainsaws 435 435E 440E 445 445E 450E and related models. Cross-reference the OEM part number from your owner’s manual with the compatibility listing to verify fitment for your particular machine.
Installation notes
Clean the screw holes and remove any thread debris. Thread the new screws in by hand first to avoid cross-threading, then tighten with the appropriate driver to the torque specified in the service manual. Do not over-tighten, as these are typically threaded into plastic or soft-metal housings.
Common questions
Q: Will these 503217321 screws fit the recoil starter on my Husqvarna 445E and 450E Rancher, or are they only for certain versions?
Yes, these screws are made for the recoil starter assembly on the Husqvarna 435, 435E, 440E, 445, 445E, 450E Rancher, 460, and 461 models. If you’re replacing the starter cover screws on one of those saws and your original part number matches 503217321, these are the correct fit.
Q: Are these the screws that hold the recoil starter housing to the chainsaw, and how many come in the pack?
Yes, these are recoil starter screws used to secure the starter assembly/cover on the compatible Husqvarna chainsaws listed. The set includes 8 screws, which is useful if you’re replacing missing, stripped, or rusted originals during a starter repair.
Q: Do I need to use threadlocker when installing these 503217321 recoil starter screws on a Husqvarna 460 or 461?
In most cases, threadlocker is not necessary if the screw holes and threads are clean and undamaged. Install them evenly and snug them down without overtightening, since the starter housing can crack or the threads can strip if too much force is used.
