Product Description:
The Hexalobular Socket Pan Head Self Tapping Screw in DIN7500 standard features a combination of Torx drive and head design, specifically engineered for applications requiring high torque and slip resistance. It is particularly well-suited for precision assembly tasks or in harsh environmental conditions.
This type of screw is commonly employed for establishing connections in various structures such as aluminum alloys, galvanized steel sheets, solar brackets, and communication base stations.
Features:
Curved Head Design:
The curved head features a supporting surface at the bottom, offering moderate load-bearing capacity with a slightly protruding surface post-installation.
Plum Blossom Groove:
Through the design of the plum blossom groove, high torque transmission can be achieved, minimizing the risk of slipping. This type of design is ideal for automated installation or applications with high torque requirements. Some variations also feature anti-disassembly properties to bolster security measures.
Reduction of Material Cracking:
To minimize material cracking, particularly in brittle plastics like PC and PMMA, internal threads are formed by extruding plastic or thin metal plates. This method not only ensures the structural integrity of the material but also lowers the likelihood of damage.
Cone or Guide Thread:
With a cone or guide thread design, the initial installation resistance is reduced, making the entire installation process smoother and more efficient.

Applications:
In the automotive manufacturing industry, Hexalobular Socket Pan Head Self Tapping Screw plays a crucial role. Thread rolling technology is utilized to improve anti-loosening properties and is extensively applied in connecting various aluminum alloy parts. Unlike traditional methods, these screws do not require tapping teeth and can be directly squeezed and locked. This feature enhances efficiency and reliability during assembly.
In industrial machinery such as machine tools and hydraulic systems, the connection points subject to dynamic loads heavily rely on the superior strength of rolled threads. This ensures stability and durability in critical components where performance is a priority. The utilization of advanced fastening solutions like Hexalobular Socket Pan Head Self Tapping Screw contributes to the overall functionality of machinery with enhanced security and longevity.
Moreover, the assembly of new energy battery modules benefits from this innovative technology. These screws find application in lithium battery brackets or metal shells, providing a secure and durable fastening method. By avoiding material weakening that could arise from traditional thread cutting, the use of thread rolling techniques ensures the integrity and longevity of the assembly, particularly in components crucial for the performance of new energy systems.
