DIN73028

DIN 73028 is a German industrial standard that specifies requirements for mechanical properties of threaded fasteners made of steel. This standard applies to screws, bolts, nuts, and other internally or externally threaded components. It defines specific grades of steel and their corresponding mechanical characteristics, such as tensile strength, yield strength, and hardness. The standard aims to ensure that fasteners used in various engineering applications possess adequate strength and reliability for their intended purpose. DIN 73028 covers different material classes and heat treatment conditions to provide a range of options for designers and manufacturers. Compliance with DIN 73028 ensures interchangeability and consistent performance of fasteners across different production batches and manufacturers.
