What are parallel pins used for?

Parallel pins serve for the friction-locked positional securing connection of components and are particularly suitable for applications that are never or only very rarely resolved. In this process, the workpieces are positively connected in the radial direction of the parallel pins.

What are the different standards for parallel pins?

Parallel pins are divided into hardened and unhardened versions. The unhardened parallel pins can be found in the DIN EN ISO 2338, formerly DIN 7. Hardened versions are standardized in the DIN EN ISO 8734, formerly DIN 6325, as well as in the DIN EN ISO 8735 (parallel pins with female thread).

What are parallel pins according to DIN EN ISO 2338?

Parallel pins according to DIN EN ISO 2338 are precision-manufactured, cylindrical fastening elements without threads, primarily used for positioning and connecting/fixing two or more parts in various applications such as mechanical engineering, electrical engineering, or the furniture industry.

What sizes of parallel pins are available?

The available sizes of parallel pins range from 0.6 h8 x 2mm to 50 m6 x 200mm, suitable for various requirements in different fields of application.

What materials are used to manufacture parallel pins?

Parallel pins are made from steel, stainless steel, or A4 quality stainless steel to ensure high durability and longevity depending on the application.

What surface roughness do the parallel pins have?

The parallel pins feature a surface roughness of Ra ≤ 0.8 µm or Ra ≤ 1.6 µm, depending on the requirement of the specific application.

Why are parallel pins important in medical technology?

In medical technology, parallel pins are of great importance due to their reliability and accuracy, as they support the strict requirements in precision and durability of this field.

What are the advantages of parallel pins?

The advantages of parallel pins include precise positioning, high compatibility with various materials, easy assembly and disassembly, reliability and longevity, cost-effectiveness, and versatility in applications.

What considerations are important when installing parallel pins?

During the assembly of parallel pins, the preparation of components, the choice of the correct fit, the use of suitable assembly tools and techniques, securing measures, as well as control and testing of the installation are essential factors.

How does compliance with standards contribute to safety?

Strict adherence to standards such as DIN EN ISO 2338 ensures the safety and reliability of parallel pins, as they meet the technical requirements and are suitable for the intended application.

What should be considered when selecting materials and dealing with corrosion?

In environments prone to corrosion, corrosion-resistant materials should be used for parallel pins, or appropriate protective measures should be taken to maintain the integrity of the connection.

Are parallel pins also custom-made to measure?

Yes, at mbo Osswald, custom-made parallel pins are possible according to your wishes. If a DIN-compliant parallel pin does not meet your specific requirements, we offer you tailor-made special parts. We develop the required component specifically for your application or manufacture according to your drawing, using the extensive material selection of our standard parts. We are able to make and implement almost any constructive change.If you already have a drawing of your desired part or want to develop a solution together with us, do not hesitate to directly contact mbo Osswald. We are ready to bring your ideas to life.
