Small countersunk head vertical stripe rivet nut din7337

Standard: din7337

Material: 304 stainless steel

Definition: small countersunk head rivet nut is also divided into smooth surface and vertical grain. It is riveted in the thin plate with chamfer. After installation, its head surface is parallel to the thin plate surface. With the development of society, especially the development and progress of China's industry, the connection mode of sheet metal has undergone earth shaking changes. From the beginning of drilling and tapping, to the later use of welded nuts, now the mainstream is the pull riveted nut, which completely replaces the welded nut in the position of sheet metal connection. The rivet nut and rivet stud are also widely used in sheet metal connection.

Industry applications:

Environmental protection equipment, medical equipment, communication equipment, electric power facilities, electronic products, food machinery, petrochemical industry, ship assembly, pump valve pipeline, building curtain wall, outdoor occasions, etc.

Why does Stainless steel screw have magnetism?

Because after cold heading and cold rolling, the molecular arrangement of stainless steel will change, resulting in micro magnetism, but this is only physical property, chemical property is not changed.
