Graphite screws have a variety of uses and are mainly used in industrial fields that require high temperature, corrosion resistance and low friction. ‌‌

Graphite screws are widely used in aerospace, petrochemical, nuclear power generation and precision instruments. Due to their high temperature resistance, graphite screws can remain stable in high temperature environments up to thousands of degrees Celsius, preventing loosening or breakage problems caused by mismatched thermal expansion coefficients. In addition, graphite screws have good corrosion resistance and self-lubricating properties, and can be used in chemical corrosive media or occasions that require frequent disassembly, extending the service life of equipment and reducing maintenance costs.

In the aerospace field, graphite screws are used to connect key components to ensure the stable operation of the system in extreme environments. Its excellent thermal conductivity and mechanical strength make it an ideal choice for manufacturing thermal conductive structural parts of spacecraft and battery insulation materials. In the automotive industry, graphite screws are used for the connection of engines, chassis and bodies, and play an important role in electrical systems. In the electronics industry, graphite screws are used to assemble and connect electronic components such as circuit boards, resistors and capacitors, taking advantage of their good conductivity and high temperature resistance
