Product Description
Screw Specifications
This individual metal screw is designed to securely fasten the drive sprocket in various chainsaw models. Located beneath the chain cover and around the guide bar, it plays a key role in keeping the chain drive assembly stable and properly aligned. To replace this screw, you’ll need to remove both the chain cover and guide bar. It features a left-hand M5 x 8.5 thread, and is intended to work with a washer (sold separately) to hold the sprocket firmly in place. If your chainsaw’s sprocket is worn, stripped, or coming loose, replacing this screw—along with the washer—is a smart way to restore a secure connection and improve performance. Sold individually, this part helps ensure your chainsaw runs smoothly and safely.
