What are parallel pins with female thread used for?

Parallel pins with female thread serve the force-fit, position-secure connection of components and are particularly suitable for applications that are never or only very rarely loosened. The workpieces are positively connected in the radial direction of the parallel pins. The female thread of the parallel pins provides additional fastening potential by enabling the screwing in of threaded pins or screws.

What different standards of parallel pins are there?

Parallel pins are divided into hardened and unhardened versions. Hardened versions are standardized in DIN EN ISO 8734, formerly DIN 6325, and in DIN EN ISO 8735 parallel pins with female thread. Non-hardened cylindrical pins are found in DIN EN ISO 2338, formerly DIN 7.

What are parallel pins with female thread according to DIN EN ISO 8735?

Parallel pins with female thread according to DIN EN ISO 8735 are precisely manufactured, cylindrical linking elements and serve for exact positioning and form-fit connection of components, with the female thread providing additional fastening options.

In which sizes are parallel pins with female thread available?

The pins are available in various sizes, from A 6 x 16 to B 50 x 200. The diameter ranges from 6 to 50 mm and the length from 16 to 200 mm.

Are special solutions possible?

Of course, in addition to the standard versions, custom solutions according to customer requirements are also feasible.

Which materials are used?

The parts are supplied in unhardened steel, hardened steel, austenitic stainless steel, or martensitic stainless steel with a surface roughness of Ra ≤ 0.8 µm.

What is the advantage of the female thread in these pins?

The female thread allows for additional fastening options by screwing in threaded pins or screws, making the connection even more secure and flexible.

Where are parallel pins with female thread mainly used?

These pins are used in numerous industrial fields such as mechanical engineering, toolmaking, plant engineering, and precision mechanics.

Which standards must be observed during the application?

Important here is the compliance with DIN EN ISO 8735 as well as additional engineering and safety standards.

How is the assembly of parallel pins with female thread performed?

The assembly is done by pressing or driving the pins into a clean, burr-free hole. The female thread can be used for additional securing.

What advantages do parallel pins with female thread offer compared to other fasteners?

Thanks to their precision, versatility, robustness and the added feature of the female thread, these pins offer a flexible and secure solution for numerous industrial applications.

What tolerances apply to the dimensions of parallel pins?

The tolerances are according to DIN EN ISO 8735. Typically in the range of m6, depending on the diameter and length of the pin. Other tolerances are possible by agreement.
