Dowel pins

What is a dowel pin?

Dowel pins are cylindrical joint elements that are mainly used to assemble and position two or more parts together, either temporarily or permanently.

Dowel pins can be smooth, threaded, grooved, ground, etc.

Dowel pins' intelligent design means they can be customised with chamfered or rounded ends, so you can adapt them perfectly to your specific application.

Dowel pins are often used in sectors where frequent assembly and dismantling is necessary, such as industrial machines, laboratory equipment and in the automotive industry.

At Gardette Industries, we have Been designing and manufacturing dowel pins for over 100 years.

Thanks to our machining capacity and over a century of know-how, we now offer a wide range of pins:

If you still don't know which pin to go with, don't panic, our team will be happy to help you choose the ideal pin for your needs.

How pins work

Cylindrical dowel pins are designed to withstand relatively low shear forces.
Pins can be used to:

  • Hold one component in place in relation to another
  • Position one part in relation to another
  • Serve as an axis within an assembly
  • Act as a safety part in an assembly

How does Gardette Industries make its dowel pins?

We use various advanced techniques and machines to manufacture our dowel pins.

In this section, we'll give you an exclusive insight into the manufacturing processes used at Gardette Industries and across the P3G group.

A machine specially designed for manufacturing dowel pins is used to shape each pin. It all begins with an iron bar, using the material that will best meet your needs to produce pins made of stainless steel, brass, steel, aluminium, etc.

Once the raw material is introduced into the machine, whether in the form of a bar or cold-drawn steel, the dowel pin manufacturing process can begin. The machine cuts the bar with absolute precision, to the exact dimensions required. Each pin is carefully cut to best satisfy your project's specific requirements.

After this crucial step, each part is carefully cleaned and oiled. This is essential to ease friction between the part and the machine, ensuring everything can operate smoothly. Lubrication also helps to extend the lifespan of each dowel pin, thus ensuring long-term strength and reliability.

At Gardette, pay great attention to detail when manufacturing our high-quality dowel pins. That's why we use specially designed machines and processes to ensure that every pin produced meets the highest of standards.

Depending on the type of cylindrical pin required, it is also possible to add chamfers or other special features using specialist machining and turning devices.

On top of this, depending on the desired application, dowel pins can also be surface treated if necessary.

The ISO 8734 / DIN 6325 dowel pin

The ISO 8734 dowel pin Is a cylindrical fastener manufactured to the German standard DIN 6325. This standard lays out the dimensions, shape, and tolerances of this pin.

ISO 8734 standard dowel pins are generally made of hardened steel, giving them high breaking strength. They are used in a variety of applications, such as:

  • Assembling mechanical parts
  • Positioning parts
  • Preventing relative movements between components

Unlike some pins, ISO 8734 dowel pins have a smooth surface, meaning that due to its very strict adjustment tolerance, it can no longer move once installed in its housing.

The ISO 8734 - DIN 6325 dowel pin is available in a variety of sizes, diameters, and lengths. Example applications include:

  • Fastening rotating mechanical parts, such as bearings or shafts
  • Positioning parts, such as bushes or screws
  • Preventing relative movements between components, such as (ring) seals.

The ISO 2338 dowel pin

ISO 2338 dowel pins are a type of cylindrical fastener manufactured according to the international standard ISO 2338.

This standard defines the dimensions, shape, and tolerances for dowel pins.

ISO 2338 dowel pins are generally made of hardened steel, giving them great breaking strength.

They are used in a variety of applications, such as:

  • Assembling mechanical parts
  • Positioning parts
  • Preventing relative movement between components

Installing conventional dowel pins



No particular knowledge or special skills are required to install ISO 8734 / DIN 6325 dowel pins. These shaft-protecting pins can be installed by anyone.

Unlike some pins, ISO 2338 dowel pins have a smooth surface, which means that due to their very strict adjustment tolerance, they cannot move once installed in their housing.

Our ISO 2338 Aand ISO 8734 - DIN 6325 standard dowel pins are available in a variety of sizes, diameters, and lengths.

Here are some example applications:

  • For fastening rotating mechanical parts, such as bearings or shafts
  • Positioning parts such as bushes or screws
  • Preventing relative movement between components, such as (ring) seals
