1.125" Shaft - Bronze Heavy Hex Castle Nut
This marine-grade bronze castle nut is engineered for 1.125-inch inboard prop shafts using a 3/4-10 NC right-hand thread. The heavy hex profile allows proper torque during installation, while the castellated top accepts a cotter pin to prevent loosening under load. Built for shaft-drive boats, this nut provides a secure, corrosion-resistant fastening solution compatible with bronze propellers and stainless propeller shafts in demanding marine environments.
