Taper Pin with Internal Thread

Definition and Standard of Taper Pin with Internal Thread

Definition: A taper pin with internal thread is a mechanical connecting piece with a conical shape and internal threads. It is mainly used for positioning and fixing in the connection of different devices.

Standard: In China, the taper pin with internal thread follows the GB/T 118-2000 standard.

Structure and Characteristics of Taper Pin with Internal Thread

Structure: The taper pin with internal thread is composed of parts such as the tapered end, threads, and the head.

Characteristics

Good Self-locking Property: The taper pin has a taper of 1:50, enabling it to form a tight connection after installation. It has good self-locking property, can withstand a certain amount of tensile force and shear force, and can effectively prevent the relative movement between parts.

Easy to Dismantle: The design of the internal threads allows the pin to be easily removed from the pin hole by using tools such as screwing in a bolt. It is especially suitable for situations where the pin hole is not through or it is difficult to remove a common taper pin.

Reusable: It is convenient to connect and easy to dismantle. Under the condition of correct use and maintenance, it can be used repeatedly without causing obvious damage to the connecting pieces.

Large Load-bearing Capacity: Compared with some other connecting pieces, the taper pin with internal thread can withstand higher axial and radial loads, and is suitable for working scenarios with large loads.

Application Fields of Taper Pin with Internal Thread

Mechanical Manufacturing: It is commonly used to connect components such as bearings, gears, and transmission shafts to achieve precise positioning and fixation between components and ensure the normal operation of mechanical equipment.

Automobile Manufacturing: It can be used to fix engine parts, chassis components, etc., to ensure the stability and reliability of various parts of the automobile during operation.

Electronic Equipment Assembly: It can connect the casings of electronic equipment, connection boards, fix wires, etc., to ensure the firmness and durability of the overall structure of the electronic equipment. At the same time, it is also convenient for disassembly and replacement during maintenance or upgrading.

Specifications and Dimensions of Taper Pin with Internal Thread

Pin Diameter: Common ones are 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, etc.

Pin Length: According to different pin diameters, there are corresponding recommended length ranges. For example, when the pin diameter is 6mm, the recommended pin lengths are 16mm, 18mm, 20mm, etc.; when the pin diameter is 8mm, the recommended pin lengths are 18mm, 20mm, etc.
