Product Description:
The Hexalobular Socket Pan Head Self Tapping Screw in ISO14583 standard is a unique fastening solution that features a Torx drive and head design. This screw is specifically engineered for high torque applications and anti-slip scenarios, making it ideal for precision assembly projects or harsh environments.
Primarily used for connecting various materials including aluminum alloys, galvanized steel sheets, solar brackets, and communication base stations, this screw offers versatility and reliability in a wide range of applications.
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, thread rolling technology is employed to enhance anti-loosening properties. This technology is widely utilized in connecting various aluminum alloy parts, eliminating the need for tapping teeth and enabling direct squeezing and locking.The connection points supporting dynamic loads in industrial machinery, including machine tools and hydraulic systems, rely on the high strength provided by rolled threads.Furthermore, in the assembly of new energy battery modules, Hexalobular Socket Pan Head Self Tapping Screws can be used in lithium battery brackets or metal shells. This application helps prevent material weakening that might occur with traditional thread cutting methods.
