Product Description:
The Hexalobular Socket Pan Head Self Tapping Screw in DIN7500
Standard combines Torx drive and head design. It is specifically engineered
for high torque applications and anti-slip scenarios, making it
ideal for precision assembly or use in harsh environments. This
type of screw is commonly utilized for connecting materials such as
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, and 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:
Hexalobular Socket Pan Head Self Tapping Screw In the automotive manufacturing industry, thread rolling
technology is used to enhance anti-loosening properties and is
widely used in the connection of various aluminum alloy parts. It
does not require tapping teeth and can be directly squeezed and
locked.
The connection points that bear dynamic loads in industrial
machinery such as machine tools and hydraulic systems rely on the
high strength of rolled threads.
There is also the assembly of new energy battery modules, which can
be used in lithium battery brackets or metal shells to avoid
material weakening caused by traditional thread cutting.
