Introduction to slotted nuts
Slotted nut is a special type of nut characterized by a groove machined on the nut, usually used in conjunction with a bolt and an open pin with holes to prevent relative rotation between the bolt and nut, thereby ensuring the stability of the connection.
The main function of slotted nuts is to fix the front and rear axles of the vehicle by tightening the screws that pass through them, tightly connecting the frame and tires together. This design is particularly suitable for equipment that needs to withstand vibration loads, such as fixing the axles of bicycles, motorcycles, and other transportation vehicles. In order to prevent the nut from loosening during use, it is necessary to use an open-ended pin to fix it through the slot of the slotted nut. The fixing of the split pin requires passing through the middle of the wheel axle screw. Usually, both ends of the wheel axle screw need to be drilled, and the diameter of the hole and the width and depth of the slotted nut groove determine the size of the split pin to be selected. When selecting appropriate wheel axle screws, split pins, and slotted nuts, the nuts can be fixed to the front wheels and frame through the wheel axle screws. The split pins secure the slotted nuts through the holes of the wheel axle screws, preventing them from loosening and ensuring that the vehicle does not loosen during movement.
Among the types of slotted nuts, hexagonal slotted nuts are the most common. They refer to a groove machined above the hexagonal nut, which is used in conjunction with a bolt with a hole in the shaft, and an open pin is inserted to prevent relative rotation between the bolt and nut. This design is widely used in various mechanical connections that require anti loosening measures to ensure the safety and stability of the equipment during operation.
Overall, slotted nuts provide reliable fixing solutions for various mechanical equipment through their unique design and use in conjunction with split pins, especially in applications that require vibration or dynamic loads
Standard for slotted nuts
Definition and purpose of slotted nuts
Slotted nut is a special type of nut that is mainly used to secure the front and rear axles of a vehicle by tightening the screws that pass through them, thereby fixing the frame and tires together. This type of nut is usually used in conjunction with bolts with holes in the shaft, and an open pin is inserted to prevent relative rotation between the bolt and nut. It is commonly used in situations where anti loosening is required.
Types of slotted nuts
There are several types of slotted nuts:
Hexagonal slotted nut: A groove is machined above the hexagonal nut and used in conjunction with a bolt with a hole in the shaft. An open pin is inserted to prevent loosening.
Type 1 hex slotted nut: The thread specification is M4-M36, divided into Class A and Class B. Class A is used for nuts with a diameter ≤ 16, while Class B is used for nuts with a diameter>16.
Type 2 hex slotted nut: thread specification M4-M36, divided into Class A and Class B, with a similar purpose to Type 1.
Relevant standards for slotted nuts
The relevant standards for slotted nuts include:
GB 6178-1986: specifies the standard for Type 1 hex slotted nuts.
GB 6180-1986: specifies the standard for type 2 hexagonal slotted nuts.
Other relevant standards, such as GB 196-81, GB 197-81, etc., involve the basic dimensions, tolerances and fits of ordinary threads, mechanical properties of fasteners, etc.

Casters, also known as universal wheels, have a structure that allows for 360 degree horizontal rotation under dynamic or static loads. This type of wheel is usually used in conjunction with fixed casters, which do not have a rotating structure and cannot rotate horizontally but can only rotate vertically. There are various materials for casters, including PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, etc. According to their load-bearing capacity, they can also be divided into micro casters, light casters, medium casters, heavy casters, and ultra heavy casters.
The window regulator motor is the power source of the window glass lifting system, responsible for driving the glass up and down. It is usually installed inside the car body or in the car door, connected to the window glass through steel wire ropes or guide rails, to achieve the control of the window lifting. The working principle of a motor is based on electromagnetic induction and changes in the direction of current. By changing the direction of current, the motor’s forward and reverse rotation can be controlled, thereby achieving the up or down movement of the car window. The start and stop of the motor are controlled by the switch inside the car, making it convenient for the driver to operate. In addition, in order to protect the motor, wire rope, and guide rail, a lubrication system is also installed in the system to provide lubricating oil for these components, reduce friction, and extend service life.
