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.
