Screws and standard DIN Screws for mechanical engineering and industry

High-quality screws and standard screws are essential for mechanical engineering and industry. Our extensive range offers the right screws for every industrial application. Whether hexagon head screws, hexagon socket head screws or special standard screws - we have exactly the fasteners you need for your projects and machines.

Our DIN screws meet the highest quality standards and are ideal for use in machines and industrial systems. We also offer a wide selection of ISO screws, which are characterized by their reliability and durability.

Standardization: What are standard (DIN / ISO) screws?

DIN screws are fasteners that are manufactured according to the standards of the German Institute for Standardization (DIN). These standards define the basic properties and dimensions of screws produced for the German market. Each type of screw has a specific DIN standard, which makes it easier to purchase and identify. The DIN standards only refer to the basic shape of the screws and not to properties such as length or strength.

In recent years, many of the DIN standards have been replaced by the internationally valid ISO standards. As a result, ISO designations are often used for screws instead of the traditional DIN designations.

What types of standard screws are there within DIN / ISO?

There are various screw shapes that are classified according to standards. The most common include:

• Hexagon head screws
• Square-head screws
• Cylinder head screws
• Countersunk head screws

The choice of screw shape depends on the respective area of application and takes into account factors such as length, size, alloy, diameter and strength class. This information is contained in the respective designation of the screw.

The most commonly used screw is the hexagon head screw. Here, many older DIN designations have already been replaced by ISO designations. For example, the designation ISO 4014 8.8 M24 x 240 galvanized indicates that it is an electrogalvanized hexagon head screw with a shank and a diameter of 24 mm, a length of 240 mm and a strength class of 8.8.

Hexagon head screws

Hexagon head bolts are one of the most commonly used fasteners in various industries, especially in mechanical engineering and industry. They are characterized by their hexagonal head, which allows for easy installation and removal using a wrench or ratchet.

Cylinder head screws

Cylinder screws, also known as cheese-head screws, are essential fasteners in numerous industrial applications. They are characterized by their cylindrical head, which enables an even distribution of force and thus ensures a high fastening strength.
