DIN 1 Taper Pin, Unhardened

The unhardened taper pin DIN 1 is a fastener used to join parts and prevent their displacement relative to one another. The tapered shape ensures a secure fit through tight contact with the holes of the mating components. The product complies with the requirements of GOST 3129-70, ISO 2339; the standard defines the material, dimensions and permissible tolerances.

Applications of DIN 1 pins

DIN 1 pins are used in mechanical engineering, automotive manufacturing, equipment and instrument production. They are used when installing shafts, axles and other rotating mechanisms, ensuring precise positioning and stable operation of assemblies. The tapered design compensates for minor discrepancies in hole dimensions and distributes the load evenly between elements.

Key properties and advantages of DIN 1 pins

DIN 1 taper pins are made from carbon and stainless steels, ensuring strength and resistance to mechanical stress. Some products have a zinc coating that protects the surface from corrosion.

Unhardened pins are distinguished by increased flexibility and ease of machining, which simplifies installation and removal.

Advantages of DIN 1 pins:

• Reliable grip between parts;
• High mechanical endurance;
• Durability and corrosion protection;
• Wide range of applications.

Pins are available in a wide range of sizes — from miniature models for small parts to large products for heavy-duty structures. The products comply with DIN, ISO and GOST standards.
