DIN screws at TOBSTEEL GmbH

DIN screws made of stainless steel


Still up-to-date and industry-standard

The world of standards is in motion. Just a few decades ago, DIN screws were the dominant standard. Today, German-speaking countries
also use connecting elements according to international ISO standards and European EN standards. However, that does not mean that
the DIN screw is by any means outdated. DIN standard screws are common in many industries and continue to prove their worth.


Why DIN standard screws are still common

There are two main reasons. Several connecting elements are only available as DIN screws because there is no need for standardization
at European or international level. For example, there is no ISO standard available for raised countersunk wood screws with a slot (DIN 95), semi-circular wood screws with a slot (DIN 96), as well as various spring washers, lock plates, wing screws and wing nuts. These DIN standard screws are often required and, of course, are included in our range. Many DIN standards are still so popular that the ISO or EN standards that have now been introduced do not really succeed in prevailing. After all, many standards have their origins in Germany, including stainless steel DIN screws. For this reason, a lot of users continue to use the DIN designation – even after the DIN standard has officially been withdrawn.


Standards are not legally binding

Legally, there is no compelling reason to use a newer ISO standard as a designation for screws that are already well known. This is because standardization institutes like DIN in Berlin are associations and not government authorities, so standards only ever come as recommended. For this reason, we prefer to stock screws under the standard used on the market. This is the quickest way for you to find the screws you are looking for. Wherever there is a second standard, we list it in brackets.

For example:

DIN 7 (ISO 2338) cylindrical pins, Form A:
The newer ISO standard is identical, but the screws are mainly traded as DIN.

DIN 931 (~ ISO 4014) hexagon screws with a shank:
The special character ~ in front of the standard indicates that the ISO standard is similar, but not completely identical.
In this case, four key widths differ.

Please download our DIN ISO product list. It provides you with a short, tabular overview of our delivery program for DIN screws
made of stainless steel. It also includes references to corresponding ISO standards as described above. Are you currently trying to
find a specific ISO or DIN standard? Then take a look at our Standards Comparison. This provides you with all standards for which
a corresponding standard exists in another class. Some of the ISO standards introduced in this way are not completely identical,
as the example for DIN 931 above shows. Before you change the standard in such cases, make sure you know for which screws
and nuts the dimensions have changed. Otherwise, it may occur that your tools do not fit as they should.
