Product Features

• Plum Blossom Groove DesignAdopting the plum blossom groove is more uniform in torque transmission compared to the traditional cross-shaped groove or single-character groove. During the tightening and loosening process, the screwdriver fits more tightly with the groove, making it less likely to slip, and it can withstand greater torque. This is particularly suitable for situations requiring higher tightening forces.
• Sunken Head DesignThe head of the screw is recessed, and after tightening, the screw head can sink below the surface of the connected part, making the connection area flatter and more beautiful. At the same time, it can avoid the exposure of the screw head from scratching other parts or the body.
• Triangular tooth structureThe tooth profile section is triangular, and this unique tooth design enables it to have good self-tapping performance and locking effect. When screwed in, it can easily cut or squeeze the material of the connected component, forming a tight threaded connection. Moreover, it is not easy to loosen under vibration or impact loads, effectively ensuring the stability of the connection.2。

Specifications and Dimensions

• Diameter SpecificationCommon diameter specifications include M3, M4, M5, and M6, among others. In some special applications, there may also be smaller or larger sizes, but they are relatively less common.
• Length RangeThe length specifications vary widely, usually ranging from a few millimeters to dozens of millimeters, such as common lengths like 6mm, 8mm, 10mm, 12mm, 16mm, and 20mm, and the specific length can be selected according to the actual connection requirements.

Material Selection

• Carbon steelGrade 4.8 and 8.8 carbon steel, with high strength and hardness, can withstand large tensile and shearing forces. The cost is relatively low, and it is suitable for general mechanical connections and structural fixation. It can be coated with zinc or other surface treatments to improve corrosion resistance.
• Stainless steelSterling materials such as 304, 316, etc., have excellent corrosion resistance and beauty, suitable for humid, corrosive environments or places with high requirements for appearance, such as outdoor equipment, food processing equipment, medical devices, etc., but the cost is relatively high.

Application field

• Electronics and appliancesIn the assembly of the casings of electronic products such as computers, mobile phones, and televisions, the design of the snowflake grooves facilitates automated assembly. The recessed heads and triangular teeth structures ensure the stability and aesthetics of the connections, effectively preventing screw looseness caused by vibration or impact, ensuring the structural integrity and safety of electronic products.
• Mechanical ManufacturingUsed for the connection and tightening of various machine tools, motors, pumps, fans, and other mechanical equipment, the triangular tooth of the self-tapping screw has the performance of simplifying the installation process to a certain extent, without the need for pre-tapping, which improves assembly efficiency. The snowflake groove and the recessed head design can meet different installation requirements and aesthetic demands, while ensuring the reliability of the connection.
• Furniture manufacturingThe use of deadheads in furniture assembly, such as tables, chairs, cabinets, and beds, can make the surface of the furniture more flat and beautiful, avoiding the exposure of screw heads that may affect the appearance and safety of the furniture. The triangular tooth structure can provide reliable tightening force to prevent the furniture from loosening during use due to shaking.
• Automobile IndustryThe use of these fasteners is widespread in the connections of various parts of the car, such as the engine, chassis, and interior. They provide reliable tightening force. The design of the snowflake grooves and triangular teeth can reduce the impact on the car's appearance, enhancing the overall beauty and safety of the car. Even under the vibration and impact during driving, these fasteners can still maintain good connection performance.
