Toolmaking: In toolmaking, these pins act as reliable fixing elements for cutting tools and precision tools. They ensure repeatable and exact handling.

Plant engineering: Here, parallel pins with female thread provide secure and robust connections of parts. They are designed to withstand high mechanical loads.

Precision engineering: In precision engineering, these pins are indispensable in the manufacturing and maintenance of precision mechanical devices. Their precision and reliability are of utmost importance.

Compatibility
Thanks to the standardized dimensions according to DIN EN ISO 8735, parallel pins with female thread are compatible with other standard parts and assembly components. This facilitates the exchange and integration into existing systems and allows for flexible adaptation to different assemblies and projects.

4. Advantages and Benefits

Precision: Parallel pins with female thread offer high dimensional accuracy, which is essential for the precise positioning of components. This accuracy ensures that the components are perfectly aligned, thereby guaranteeing the flawless function of the entire assembly.

Versatility: These pins are suitable for a wide range of industrial applications. They can be used in fields such as mechanical engineering, tool manufacturing, plant construction, and precision mechanics. This versatility makes them an indispensable part of numerous production processes.

Durability: Made from high-quality hardened materials like steel and stainless steel, parallel pins with female thread are characterized by their high load capacity and longevity. This durability ensures that the pins perform reliably even under demanding conditions and frequent use.

Additional Function – female thread: The female thread of the parallel pins provides expanded mounting options. It allows the screwing in of threaded studs or screws, offering additional fixing possibilities and a more secure fastening of components. This additional function significantly expands the application range of the pins, making them a flexible solution for various use cases.

Due to these special properties and functions, parallel pins with female thread offer numerous advantages, making them a crucial element in industrial manufacturing and assembly.

5. Assembly and Installation

Step 1 - Preparation of the bore: Before the parallel pin with female thread is mounted, it is essential that the bore is clean and free of burrs. This ensures that the pin can be inserted accurately and a secure connection is guaranteed. Dirt and burrs in the bore can hinder the assembly and affect the stability of the connection.

Step 2 - Pressing or driving in: The actual assembly is done by pressing or driving the parallel pin into the prepared bore. It is important to apply even pressure to avoid damage. This ensures a stable and permanent fixation of the pin in the component.

Step 3 - Using the female thread: After the assembly, the integrated female thread can be used for additional securing. Screws or threaded pins can be screwed in to further stabilize the connection and secure the fastening. This additional fixation increases the reliability and load-bearing capacity of the entire construction.

A clean and careful assembly step ensures that the parallel pin with female thread can achieve its full functionality and strength. Using the female thread provides an additional method for stabilizing and fixing the components, making the application possibilities even more diverse.

Step 4 - Inspection and testing: After the assembly, it is crucial to inspect the installation to ensure that the fit and alignment of the components meet the specifications. A thorough inspection helps to identify and correct assembly errors before the assembly is put into operation.

6. Safety instructions & Standards

Protective equipment: During the assembly of parallel pins with female thread, wearing appropriate protective equipment is essential. Safety goggles protect the eyes from flying particles and shavings, while gloves protect the hands from injuries and skin irritations. These precautions significantly contribute to preventing workplace accidents.

Tools: Use only intact and task-appropriate tools. Defective or unsuitable tools can lead to faulty assemblies and injuries. Additionally, suitable tools ensure a safe, precise, and efficient installation of the parallel pins.

Compliance with standards: When assembling and using parallel pins with female thread, it is crucial to observe the relevant standards. Adherence to DIN EN ISO 8735 is particularly important. This standard outlines the requirements for parallel pins that must be met for safe and reliable use. Furthermore, supplementary engineering and safety standards should be considered to ensure the highest safety and quality standards.

Overview of various standards: The hardened parallel pins are found in DIN EN ISO 8734, previously DIN 6325. Another hardened version with additional female thread is standardized in DIN EN ISO 8735. Unhardened versions are standardized according to DIN EN ISO 2338, previously DIN 7.

Frequently Asked Questions (FAQ)

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.
