For crying out loud, Richard, You've got to take some calipers to the boat and measure the od of the threads, and take a rule and measure the threads per inch, and the number per millimeter - C&C had both metric and inch on these boats. Failing that, take some pictures and take the nut to a machine shop. Did you get the picture I sent you of the top of my rudder? Most bearing nuts will be in millimeters, as this https://www.skf.com/group/products/rolling-bearings/accessories/lock-nuts/integral-locking and the one shown here is not beefy enough for what you need. Too bad I didn't keep my buddy's bent C&C37 Rudder.
