SS304 DIN7982 M3.9 CSK Head Self-tapping Screws

Made from 304 stainless steel, it boasts rust and corrosion resistance, maintaining stable performance in humid or corrosive environments.Its self-tapping design allows it to penetrate materials directly without pre-drilling, simplifying the installation process. The countersunk head ensures a flush finish, ideal for applications where the screw head needs to be hidden. The screw's strong bearing capacity makes it suitable for penetrating thicker materials and withstanding significant tensile and shear forces.

This SS304 DIN7982 M3.9 CSK Head Self-tapping Screws is manufactured in full compliance with the DIN7982 standard, with strict quality and specifications. ​

It is made of 304 stainless steel, which has excellent corrosion resistance and is not easy to rust. It can be used for a long time in complex environments such as humidity. It can adapt to food processing equipment, medical equipment and other industries with extremely high requirements for hygiene and corrosion resistance. The M3.9 specification has a thread diameter precisely controlled at 3.9mm, ensuring compatibility with various workpieces and meeting different assembly requirements. The countersunk head (CSK Head) design is very practical. When the screw is installed, its head can be flush with the installation plane or slightly lower than the plane, making the overall surface smoother. It is not only beautiful, but also avoids collision hazards caused by protrusions. It has obvious advantages in furniture manufacturing, electronic equipment housing assembly and other scenarios. ​

As a self-tapping screw, it has a unique self-tapping function. During installation, there is no need to pre-fabricate threaded holes in advance. It can directly penetrate metals, plastics and other materials. The threads are formed by extruding and cutting materials with its own threads, which greatly simplifies the installation process and improves work efficiency. It can play an important role in small equipment maintenance, simple structure construction, etc. Whether it is outdoor facilities that pursue durability or indoor products with high requirements for appearance and hygiene, this screw is an ideal choice.
