MS Castle Nut
MS (Mild Steel) Castle Nut, also known as a castellated nut, is a hexagonal nut with slots or notches cut into one end. These slots allow a cotter pin or split pin to pass through a hole in the bolt, locking the nut in place and preventing it from loosening due to vibration or movement. Made from mild steel, MS castle nuts are widely used in applications where secure and safe fastening is required.
