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.

Introduction: Automotive glass lifters are generally composed of the following parts: control mechanism (rocker arm or electric control system), transmission mechanism (gear, toothed plate or rack, gear flexible shaft meshing mechanism), glass lifting mechanism (lifting arm, motion bracket), glass support mechanism (glass bracket) and stop spring, balance spring. The basic working route of a glass lifter is the control mechanism → transmission mechanism → lifting mechanism → glass support mechanism. The balance spring is used to balance the gravity of the glass to reduce the operating force; The stop spring installed between the small gear and the support seat is used to hold the glass (stop) and ensure that it stays in the required position.
