Castle Nut 1.500"

1.500" Shaft - Bronze Heavy Hex Castle Nut

This bronze heavy hex castle nut is intended for 1.500-inch inboard propeller shafts with a 1 1/8″-7 NC right-hand thread. The increased thread diameter and heavy hex design support higher torque requirements common on larger shaft systems, while the castellated top allows for cotter pin locking to maintain secure retention. Cast from marine-grade bronze, this nut delivers long-term corrosion resistance and dependable performance in heavy-duty shaft-drive marine applications.
