DIN 7xxx

Within the industry, DIN 7xxx standards play an important role in precise positioning, fastening, and mechanical connections. These standards were developed by the Deutsches Institut für Normung (DIN) and cover various types of fasteners and fitting devices, such as pins, keys, retaining springs, and other mechanical components that ensure a stable and reliable structure. DIN 7xxx products are widely used in sectors such as mechanical engineering, agricultural technology, and heavy industry, including offshore and petrochemical applications. You can order them from Hetraco. We maintain high quality standards and hold ISO 9001 and 14001 certifications.

Manufactured according to strict dimensions and tolerances

DIN 7xxx products are manufactured to strict dimensions and tolerances, ensuring a consistent fit and reliable performance. This helps minimize wear, play, and malfunctions, and contributes to a longer service life for machines and structures. Thread rolling also contributes to strong and durable connections, as the threads are formed under high pressure for added load-bearing capacity. The standardized parts ensure efficient maintenance and easy replacement of components. Especially in industries where equipment runs continuously and is subjected to heavy loads, our specialty products are crucial for minimizing downtime.
