SS304 DIN7982 M4.8 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.

SS304 DIN7982 M4.8 CSK Head Self-tapping Screws is a fastening tool that combines high-quality materials and precise specifications. The 304 stainless steel it uses contains 18% chromium and 8% nickel, also known as 18/8 stainless steel. It has excellent corrosion resistance and is durable in all kinds of environments. It effectively reduces the risk of rust and corrosion and is suitable for food processing equipment, medical equipment and other fields that have strict requirements on material corrosion resistance. At the same time, the material is non-magnetic in the annealed state, can be hardened by cold working, and can maintain good strength and toughness in low temperature environments. ​

This self-tapping screw is manufactured in strict accordance with the DIN7982 standard to ensure dimensional accuracy and quality stability. The M4.8 specification and precise thread diameter can provide reliable fastening force in practical applications. The countersunk head (CSK Head) is uniquely designed. When the screw is installed in the hole, it can be flush with the surface of the surrounding material or slightly lower than the surface, which not only ensures the overall appearance of the flatness and beauty, but also avoids the safety hazards caused by the protruding parts. It can also effectively reduce the interference with other components, and is suitable for occasions with high requirements for surface flatness. ​

The self-tapping function is a highlight. During the process of screwing into the material, it can cut out the thread by itself without pre-tapping, which greatly improves the installation efficiency, especially for hard substrates such as metal and hard plastic. However, it should be noted that the hardness and depth of the processed material should be within a reasonable range. Its cross groove design makes it easy to use the corresponding screwdriver for operation, making the installation and removal process more convenient and smooth. ​

SS304 DIN7982 M4.8 CSK Head Self-tapping Screws, with its excellent material performance, precise specification design and practical functions, has become an ideal choice for many industries such as construction, machinery manufacturing, and furniture production in the fastening connection link. ​
