10FSX  (Handle Nut (Check Cross Compatibility)

Genuine Shimano Handle Nut (part #10FSX, BNT2049 / TGT0647) — the handle nut secures the reel handle to the drive shaft, keeping it firmly attached through thousands of cranking cycles and heavy fish-fighting loads. If the handle nut becomes stripped, corroded, or loosened, the handle can wobble or detach, leaving you unable to retrieve line when it matters most. Cross-references with Shimano part numbers 10FSX, BNT2049, and TGT0647 — check cross-compatibility with your specific reel model. OEM replacement ensures perfect fit and factory performance.
