2.500" Shaft - Bronze Heavy Hex Castle Nut
This bronze heavy hex castle nut is engineered for 2.500-inch inboard propeller shafts with a 1 3/4″-5 NC right-hand thread. Intended for very large shaft systems, the heavy hex design allows controlled, high-torque installation while maintaining full thread engagement. The castellated top supports cotter pin locking to provide a mechanical safeguard against loosening in service. Cast from marine-grade bronze, this nut offers excellent corrosion resistance and dependable performance for large yachts, commercial vessels, and heavy-duty shaft-drive marine applications.
