Countersunk Head Grooved Pin

The countersunk head grooved pin is a kind of mechanical connecting pin with specific structure and application. The following is a detailed introduction to the countersunk head grooved pin:

Structural Features of the Countersunk Head Grooved Pin

Head: It is in the shape of a countersunk head, that is, the head is in the form of a truncated cone. After the pin is installed, it can be flush with or slightly lower than the surface of the connected part, thus ensuring the flatness of the connecting surface and avoiding interference or scratching other components due to protrusion during use.

Grooves: There are longitudinal grooves along the length direction of the pin body, which are usually evenly distributed. These grooves enable the pin, after being inserted into the pin hole, to adapt to different hole diameter tolerances through elastic deformation, improving the tightness and reliability of the connection. At the same time, they increase the friction between the pin and the connected part, preventing the pin from loosening during use.

Pin Body: Generally, it is cylindrical. The surface has been processed to have a certain precision and surface finish to ensure the fitting accuracy with the pin hole.

Materials and Properties of the Countersunk Head Grooved Pin

Materials: Medium carbon steel or medium carbon alloy steel, such as 45 steel, 40Cr, etc., are often used to meet the strength and toughness requirements of general mechanical connections. In some occasions with special requirements, stainless steel or other special materials are also used to improve the corrosion resistance, wear resistance and other properties of the pin.

Properties

High Strength: It can withstand large shear force and tensile force, ensuring a firm connection.

Good Toughness: It is not easy to undergo brittle fracture under impact or vibration loads, and has high safety in use.

Good Wear Resistance: After appropriate heat treatment and surface treatment, the countersunk head grooved pin has good wear resistance and can maintain good performance during long-term use.

Application Fields of the Countersunk Head Grooved Pin

Mechanical Manufacturing: It is used for the assembly of various mechanical equipment, such as connecting gears, chain wheels, pulleys and shafts, as well as the connection and positioning between components such as casings and brackets. It can make the connecting surface flat, facilitating the installation and operation of other components.

Automobile Manufacturing: It is widely used in the assembly of components such as automobile engines, transmissions and chassis. For example, it is used to fix the components of the engine cylinder block and connect the components of the chassis suspension system. It can not only ensure the reliability of the connection, but also make the surface of the connection part flat, meeting the overall appearance and structural requirements of the automobile.

Electronic Equipment Manufacturing: It is often used for the assembly of the casings of electronic equipment, the fixation of internal connection boards, etc. It can make the surface of the equipment smooth, prevent the appearance and use of the equipment from being affected due to the protrusion of the pin head, and at the same time ensure the firmness of the connection, meeting the requirements for precision and reliability of electronic equipment.

Furniture Manufacturing: It is applied in the connection of mortise and tenon structures of furniture or other parts that require hidden connections. The countersunk head design can ensure that the connection points do not affect the aesthetic appearance of the furniture. At the same time, the structure of the grooved pin can provide reliable connection strength, ensuring the structural stability of the furniture.

Specifications and Dimensions of the Countersunk Head Grooved Pin

Diameter: Common diameters are 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, etc. For different application scenarios, an appropriate diameter needs to be selected according to the hole diameter of the connected parts and the force-bearing situation.

Length: The range generally varies from 6mm to 200mm, and the specific length is determined according to the thickness of the actually connected parts and the installation requirements.

Parameters of the Grooves: The number of grooves is usually 3, 4 or 6, etc. The width and depth of the grooves also have corresponding standard dimensions to ensure the elasticity and connection performance of the pin.
