SS304 DIN7982 M3.5 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 headneeds to be hidden. The screw's strong bearing capacity makes it suitable for penetrating thicker materials and withstanding significant tensile and shear forces.

SS304 DIN7982 M3.5 CSK Head Self-tapping Screws, that is, 304 stainless steel, DIN7982 standard, M3.5 countersunk self-tapping screws, are extremely practical fastening components in industrial and daily applications. ​

The thread diameter of this screw is 3.5mm. The countersunk head design allows it to be flush with the surface of the connected material after installation. It is not only beautiful, but also effectively avoids interference or safety hazards caused by protrusion. The cross slot design is easy to operate with the corresponding screwdriver, providing reliable torque transmission, making the installation process more convenient and efficient. ​

The use of 304 stainless steel is a highlight. 304 stainless steel has good corrosion resistance and is not easily corroded, rusted or stained when exposed to water and other environments like ordinary steel. However, in low-oxygen, high-salinity or poor air circulation environments, its anti-fouling performance will be weakened. But in general indoor and outdoor environments, as well as most industrial application scenarios, 304 stainless steel is sufficient to cope with various challenges and meet long-term use needs.​

Manufactured according to DIN7982 standard, it ensures high precision and interchangeability of the product. The standard has strict regulations on the size, tolerance, mechanical properties and other aspects of the screws, so that each screw has stable and reliable quality. The self-tapping function is a practical feature of this product. During installation, it can tap the thread on the material by itself, which is suitable for harder substrates such as metal and hard plastic (of course, there are certain reasonable restrictions on the hardness and depth of the substrate). When using it, it is recommended to drill a suitable guide hole first, which will make the self-tapping process smoother and also help to improve the firmness of the connection. ​

SS304 DIN7982 M3.5 CSK Head Self-tapping Screws are widely used in machinery manufacturing, electronic equipment assembly, furniture production and other fields, and are ideal for reliable fastening connections.
