Description:Hexagonal slotted nuts are designed for use with bolts with holes at the end of the screw. They are grooves machined on the top of ordinary hexagonal nuts (referring to the six sides of the nut). There is a groove on each of the six sides. Hexagon slotted nuts are used in conjunction with bolts with holes and cotter pins to prevent relative rotation of bolts with holes and hexagonal slotted nuts. The nut fixes the front wheel and the frame by the axle screw, and the split pin fixes the hexagonal slotted nut with the hole fastener of the axle screw, so that the hexagonal slotted nut will not loosen even when the vehicle is running. It is more commonly used in the occasion of vibration load or alternating load.
