The function of the slotted nut is to fix the front and rear axles of the vehicle by fastening the threaded rods passing through the front and rear wheel axles, so that the frame and tires are fixed together. In order to prevent the nut from loosening, the slotted pin must be used to fix the slotted nut through the slot of the slotted nut. To fix the slotted nut, the slotted pin must pass through the middle of the axle threaded rod. Generally, both ends of the axle threaded rod need to be drilled, The diameter of the hole and the width and depth of the slot of the slotted nut determine the specification of the cotter pin. When the axle screw, the cotter pin and the slotted nut are relatively matched, the nut will fix the front wheel and the frame through the axle screw, and the cotter pin will hold the slotted nut through the hole fastener of the axle screw, so that the slotted nut will not loose and the vehicle will not loose when moving.
For the connection where the head of the slotted nut is slightly higher or flat than the plane of the fixed part, a hexagon nut slightly smaller than the outer diameter of the head of the slotted nut can be used to place it on the head of the hexagon slotted nut, and then spot weld the nut with the head of the hexagon slotted nut. After cooling, screw the nut with a movable handle to take out the hexagon socket bolt.

The hexagon slotted nuts can be divided into stainless steel hexagon slotted nuts CLS type, fast cutting steel hexagon slotted nuts S type, stainless steel hexagon slotted nuts SP type and copper and aluminum hexagon slotted nuts CLA type, which should be used in different environments. Its specification is usually from M2 to M12. There is no uniform national standard for hexagon slotted nuts, which are often used in chassis, cabinet and sheet metal industry.
