Castle Nut 1.750"

1.750" Shaft - Bronze Heavy Hex Castle Nut

This bronze heavy hex castle nut is manufactured for 1.750-inch inboard propeller shafts with a 1 1/4″-7 NC right-hand thread. Designed for large-diameter shafts, the heavy hex profile supports high torque installation, while the castellated top allows for cotter pin locking to prevent backing off under load. Produced from marine-grade bronze, this nut offers excellent corrosion resistance and is well suited for heavy-duty shaft-drive vessels and commercial marine applications.

Thread Size: 1-1/4"-7 NC-RH
