Introduction to Splint Nut
A splint nut, also known as a slotted nut or a castle nut, is a type of nut with slots or notches cut into one end. These slots are designed to accommodate a cotter pin or a safety wire, which is inserted through a hole in the bolt or stud to prevent the nut from loosening due to vibration or other dynamic forces. Splint nuts are widely used in various industries, including automotive, aerospace, machinery, and construction, where reliable fastening and safety are of utmost importance.
