DIN 7 Non-Hardened Dowel Pin

Cylindrical pin DIN 7 is a fastener used to secure parts and ensure a reliable connection. The shape is cylindrical, the material is carbon or stainless steel. Pins can be hardened or non-hardened, which determines their strength and load resistance. Complies with GOST 3128 and ISO 2338.

Applications of DIN 7 pins

The DIN 7 cylindrical pin is used in mechanical engineering, construction, machine-tool building, instrument making and other industries. Suitable for installing various structures where precision and reliable connections are required. The fastener helps align structural elements relative to each other, ensuring correct positioning and preventing displacement.

Advantages of the DIN 7 pin

• Suitable for connections with small size and low loads;
• Steel material provides resistance to deformation;
• Compliance with DIN, ISO and GOST standards guarantees interchangeability with equivalents;
• Installation does not require special tools.

Materials and design of DIN 7

Pins are made primarily of carbon steel, which provides high strength and durability. Depending on operating conditions, stainless steels resistant to corrosion and aggressive media may be used. Non-hardened steel is used where flexibility and the ability to deform are important, while hardened versions provide increased hardness and wear resistance.

Standard sizes of the DIN 7 pin vary in length and diameter. Length can range from 3 to 160 millimeters, depending on the requirements of the specific project. Diameter is usually measured in millimeters and also varies over a wide range (from 1 to 30 mm). These parameters allow selecting the optimal option for any type of connection.
