Carburized Steel Black Zinc Torx Pan Head Self Tapping Screw GB2670
Carburized steel black zinc Torx pan head self tapping screw GB2670 is a high-performance fastening component designed for sheet metal, machinery, and industrial assembly applications requiring strong thread forming capability and reliable surface protection. The carburized steel black zinc Torx pan head self tapping screw GB2670 is manufactured from carburized carbon steel with a black zinc coating, providing enhanced surface hardness, wear resistance, and corrosion protection.
The carburized steel black zinc Torx pan head self tapping screw GB2670 features a Torx drive recess, pan head design, and flat tail point structure, allowing efficient installation and stable fastening performance without pre-threaded holes in many applications.
Product Overview
The carburized steel black zinc Torx pan head self tapping screw GB2670 is a precision self tapping fastener manufactured according to GB2670 requirements. It is designed to create its own threads when installed into suitable materials such as steel sheets, plastic components, and thin metal structures.
The carburizing treatment increases the surface hardness of the screw while maintaining a tough core, improving resistance against wear and installation stress. The black zinc coating enhances appearance and provides additional protection against oxidation.
The Torx drive design improves torque transmission compared with traditional cross recess screws. The carburized steel black zinc Torx pan head self tapping screw GB2670 is widely selected for applications requiring strong driving performance, accurate installation, and long-term fastening reliability.
