Gardette Group, threaded dowel pin manufacturers - DIN 7979D - ISO 8735



Today, the Gardette group is one of Europe's leading manufacturers of extractable (threaded) dowel pins, DIN 7979D - ISO 8735. These mechanical components are designed for applications that require precise fastening, but also must be easily dismantled when necessary. The ISO 8735 standard defines industry technical standards for threaded pins, ensuring quality, reliability and compatibility for many different industrial applications.


DIN 7979D standard pins are notable for their unique design, including their internal thread which makes them easy and safe to dismantle using an extracting screw. These pins are ideal for applications that require regular maintenance or adjustments.

They are available in different standard lengths and diameters, but can also be customised to meet clients' specific requirements.

What are the different types of cylindrical pins?


Pins can undergo different finishing processes to meet particular requirements:


Our pins are made on site in Villefranche-sur-Saône, France, with meticulous quality control in order to ensure our products are in line with international standards.

Our dowel pins are generally made of C45 steel, a carbon steel that offers good mechanical strength. This material can also be treated to enhance its performance, e.g. through:

  • Case-hardening: To improve surface hardness and abrasion resistance.
  • Nitrocarburising: For long-lasting protection against wear and tear and corrosion.
  • Phosphatising: A cost-efficient treatment that enhances adhesion and reduces corrosion risks.
  • Galvanising: For increased corrosion resistance.

Made-to-order custom dowel pins with internal threads, DIN 7979D - ISO 8735


With over 100 years of machining expertise, we also offer made-to-order solutions, including drilling, tapping and specific sizing for precise technical needs.


Why opt for DIN 7979D / ISO 8735 extractable dowel pins?


DIN 7979D standard extractable threaded dowel pins are widely used for numerous industrial uses, such as:

  • Mechanical engineering: For assemblies that require frequent interventions.
  • Transmission systems: Ensuring sturdy fastening while remaining easy to dismantle for maintenance.
  • Rotating parts: Offrant une fixation précise et durable tout en permettant des ajustements rapides. Offering precise, durable fastening but still allowing for quick adjustments.
  • Machine tools: For assemblies that need to combine both sturdiness and practicality.


Whether you're looking for standard or personalised solutions, our DIN 7979D pins are the perfect mix of reliability, precision and practicality, allowing them to meet the highest industry standards.
