10K34  (RD16231  Nut Lock Plate)

Genuine Shimano Nut Lock Plate (part #10K34, RD16231) — the nut lock plate secures critical fasteners inside the reel body, preventing nuts from loosening due to vibration and rotational forces during use. Without a functioning lock plate, internal nuts can back out, leading to play in the drive train, wobbly components, and potential catastrophic reel failure. Cross-references with Shimano part numbers 10K34 and RD16231. OEM replacement ensures perfect fit and factory performance.
