Cotter pins, rings or split rings

We just get ours from our swage suppliers, (for their closed body rigging screws). But i guess any fastening wholesaler should have the same.

Most all SS screws have locking nuts, especially in smaller sizes. It's not bad but also not so wonderful to use an SS nut over a bronze stud. Even if you have bronze on bronze, stressing the threads like that is progressivly less secure and less durable as the size of the turnbuckle increases. So, as the size goes up, so does my personal prejudice against locking nuts.

However, that's not science, just gut.
