1/2-13 Castellated Nuts

Hex Castle Nuts or Castellated Nuts have notches on one end, which resemble the serrated tops of castle parapets. These nuts are used with a bolt with cross-drilled holes, so that a cotter pin can pass through the nut and into a hole in a bolt shank, thus preventing the nut from loosening. The notched end is turned down slightly, allowing the cotter pin to be bent around the nut. Often used in machinery, shafts and automotive applications.
