Recoil Starter Screws Replacement for Husqvarna Chainsaws 340, 345, 350, 435, 440, 445, 450, 455 Rancher, 455 Rancher II, 460 & 461-503217321 (4 Pack)

What It Is

This is a 4-pack of replacement recoil starter screws (OEM part #503217321) for Husqvarna chainsaws. They secure the recoil starter assembly to the saw’s crankcase. Use them when original screws strip, break, or get lost during starter replacement or maintenance.

Fitment & Compatibility

• Exact models: Husqvarna 340, 345, 350, 435, 440, 445, 450, 455 Rancher, 455 Rancher II, 460, and 461.
• Check before buying: Count the screws on your current starter—these are typically 3 per saw, but the pack gives you 4 for spares. Measure thread length (approx. 12mm) and head diameter (8mm). Confirm your saw uses a Phillips head (not Torx or hex). These are OEM Husqvarna, not aftermarket—no fitment issues if your model is listed.
• Don’t assume cross-brand fit: These will not work on Stihl, Echo, or other brands. If your model isn’t in the list, measure your old screw first.

Key Things to Know

• Quality: OEM-grade steel with corrosion-resistant coating. Harder than cheap aftermarket screws—less likely to strip during tightening.
• Installation: Easy—just unscrew the old ones and replace. Use a manual screwdriver (not an impact driver) to avoid over-torquing. Torque spec is 3-4 Nm (hand-tight plus a quarter turn).
• Common gotcha: The starter housing threads can be damaged if you cross-thread. Start screws by hand, then tighten evenly in a star pattern.
• Value: $2 per screw is fair for OEM. Aftermarket packs may cost less but often use softer metal that strips.

Should You Buy It

If you own any of the listed Husqvarna models and need to replace lost, stripped, or broken recoil starter screws, this is the right buy. It’s cheap, OEM quality, and includes a spare. Avoid if you need screws for a different brand or model—measure first.
