A welding screw is a thick cylindrical metal rod. On the surface of which there is a carving and a rounded protrusion on one side.
The field of application is in products where high precision and strength of the connection of the threaded element and thin-walled metal is required, where it is impossible to apply another technology. It is used in those cases when the connection must have a high resistance to tearing and twisting, and the thickness of the metal sheets is not sufficient to use other types of fasteners to obtain a reliable connection.
The material of manufacture is steel
Coating Zinc (Plated) protects against corrosion, if it is planned to use fasteners in aggressive conditions.
