Locknuts for use with Cotter Pin (Castle Nut)

These locknuts are used to fasten spinning components that are prone to slight vibration, such hand trucks and cart wheels. Because the pin can shear under continuous stress, they are not advised for use on parts that are subjected to significant vibration. Although you can reuse these nuts, each time you use them, a new cotter pin is required.
