Genuine Shimano Eared Washer B (part #10BWF), also cross-referenced as RD0579. This specialty eared washer is used inside Shimano spinning reels to provide secure retention for internal assemblies. The eared design features tabs that lock into place, preventing the washer from rotating and keeping critical components properly aligned during high-speed retrieves and hard fish fights.
