Slotted nuts mainly refer to hexagonal slotted nuts, that is, a slot is machined above the hexagonal nut. It is used in conjunction with a bolt with a hole in the screw and a split pin to prevent the bolt from rotating relative to the nut. Hexagon slotted nuts are divided into stainless steel hexagonal slotted nuts CLS type, fast-cutting steel hexagonal slotted nuts S type, stainless iron hexagonal slotted nuts SP type and copper and aluminum hexagonal slotted nuts CLA type, respectively. Different use environments. Its specifications are usually from M2 to M12. There is no uniform national standard for hexagonal slotted nuts, and they are often used in cabinets and sheet metal industries.
