The tin nuts are called pal nuts. When they are tightened properly according to the shop manual the nut jambs the threads of the regular nut preventing it from coming loose. They were first used in 1940. Prior to that they had cotter pins. The pal nuts should not be reused. Thet were eleminiated in 1955.
