Product Description:
The Hexalobular Socket Pan Head Self Tapping Screw in DIN7500 standard incorporates a Torx drive and head design, tailored for high torque and slip-resistant applications. This makes it particularly well-suited for precision assembly in challenging environments. It is commonly employed in the connection of aluminum alloys, galvanized steel sheets, solar brackets, and communication base stations.
Features:
Curved head with supporting surface at the bottom, providing moderate load-bearing capacity, slightly protruding surface after installation. The design of the plum blossom groove can achieve high torque transmission, reduce the risk of slipping, and is suitable for automated installation or high torque requirements.
Some models support anti-disassembly to enhance security. By extruding plastic or thin metal plates to form internal threads, material cracking can be reduced (especially suitable for brittle plastics such as PC and PMMA). Cone or guide thread design reduces initial installation resistance.

Applications:
In the automotive manufacturing industry, the Hexalobular Socket Pan Head Self Tapping Screw is widely utilized. This screw type employs thread rolling technology to improve anti-loosening properties, especially in connecting various aluminum alloy parts.
Unlike traditional screws, the Hexalobular Socket Pan Head Self Tapping Screw does not require tapping teeth. Instead, it can be directly squeezed and locked, providing a secure connection. This technology is particularly beneficial for connecting points that endure dynamic loads in industrial machinery like machine tools and hydraulic systems.
Moreover, thread rolling technology is employed in the assembly of new energy battery modules. By using these screws in lithium battery brackets or metal shells, it helps prevent material weakening that can occur with traditional thread cutting methods.
