Introduction In normal cases, standards are checked every 5 years to ensure that they still correspond to current state-of-theart technology. This is an important measure, including from a legal standpoint. Ignorance of or noncompliance with current standards and the cross-references contained within them frequently results in complaints or even damage to property. Over the years, many DIN standards have been replaced by internationally applicable DIN EN ISO standards. For export-oriented companies, it is essential to know which standards are applicable and which have been retracted. Should a repair be necessary, the customer or installer must be able to acquire appropriate state-of-the-art fasteners. In the case of a warranty claim, the manufacturer must prove compliance with all rules which were applicable at the time of commissioning. In practice, it is still the case today that many users still use products which have been retracted and replaced by products compliant with successor standards or even products compliant with standards which have been retracted without being replaced. The result is increased inventorying and material planning effort on the part of fastener dealers. The sometimes small demand from fabricators for current standards can also negatively affect purchase prices, as manufacturers only produce small quantities. Products compliant with retracted standards should, at a maximum, only be used for spare part needs. In cases where standards were retracted without replacement, for example because their functionality was not guaranteed or in cases where standards have been revised for safety reasons, it is absolutely necessary to take state-of-the-art technology into account. This book is intended for use as an aid in switching over from retracted DIN standards to current EN and/or ISO standards. It contains information on changes to different product standards which are relevant to use.

1. Product designations and product changes Many DIN standards formed the basis for ISO standards. Oftentimes, slight modifications were made to previous DIN standards to create the ISO standards applicable today. If an ISO standard is adopted into national bodies of standards unchanged, the national standard is given the same designation as the corresponding ISO standard. The only change is the addition of the DIN EN abbreviation to the name. Accordingly, a nut compliant with ISO 4032-M12-8 has that name everywhere in the world. The German edition of the standard would then be DIN EN ISO 4032-M12-8. The changes to names in merchandise management systems, drawings and part lists often require considerable effort to make, but these adjustments are unavoidable if a company wants to continue to be successful. If state-of-the-art technology (product safety law) is not used, the amount of money which would have been saved by using the inferior product can be exceeded several times over should property be damaged as a result of that use.
2. Standardization work In the past, this standardization work within Germany was carried out on a national level by the Deutscher Institut für Normung e. V. (DIN), or the German Standardization Institute. In addition, on a European level there are also the EN standards, and on an international level the ISO standards, issued by the International Organization for Standardization. 2.1 DIN National standards (DIN) will be/have been replaced by international/European standards in most cases. DIN standards will only remain in place for products which do not have, or will not receive, ISO or EN standards. 2.2 ISO International standards (ISO) are, according to the mission and objectives of the ISO (founded 1946), aimed at the global standardization of technical rules and thus the simplification of exchange of goods and the removal of barriers to trade. 2.3 EN European standards (EN) are aimed at the harmonization of technical rules and laws on the European market (EU/EEC), which was launched on 1/1/95. Basically, existing ISO standards are to be adopted unchanged (to the greatest degree possible) as EN standards. The difference between ISO and EN standards lies in the fact that EN standards must be adopted and introduced immediately and unchanged as national standards after being passed by the European Commission, and the corresponding national standards are to be retracted at the same time.

3. Small screws with slot and Phillips drive When ISO standards were introduced for small screws, some of the head heights and head diameters of the screws were changed. For most applications, these changes do not cause any problems. A close look at the changes is only necessary in cases where very little installation room is available. The general changes and ISO successor standards are listed in Table 1. Table 2 contains the head measurements of the DIN standard and the ISO successor standard.

4. Small screws with hexagon socket and hexalobular drive In Germany, established product standards such as DIN 6912 and DIN 7984 still apply. So far, no ISO successor standards have been created for these standards. DIN 7991, on the other hand, has been replaced with ISO standard 10642. With these countersunk screws, it must be noted that the countersinking was is carried out as per DIN 74 shape F. In addition, standards for hexalobular drive (TX) screws have been introduced over the past few years. There were no DIN standards for these screws. The head geometry corresponds to Phillips-drive screw heads with the exact shame shape. Table 3

5. Screws with hexagon head drive For most of these screw types, the DIN standards were retracted many years ago. The ISO successor standards largely correspond to the retracted DIN standards. For this reason, there are in principle no limitations on use. It must be noted, however, that other sizes must be used with the fastening tools for sizes M10, M12, M14 and M22. The dimensions of the wrench sizes can be seen in Table 7.

6. Screws with standard high-profile fillister head DIN standard 912 has been replaced by ISO standard 4762. The ISO successor standard no longer includes some of the nominal diameters from the DIN. An additional standard has also been put out for screws with a metric fine thread. Geometrically, ISO 4762 corresponds to DIN 912; limitations on use are not to be expected. In addition, a fillister head screw with hexalobular drive (TX) was standardized. In comparison to the hexagon socket drive, improved force transmission and less drive wear are possible with the hexalobular drive. Table 8

7. Sheet-metal screws When switching over the DIN standards for sheet-metal screws to ISO standards, some of the head heights and head diameters were changed. In the case of countersunk head screws, the head angle has also changed from its previous 80° to the current 90°. When countersinking, the dimensional definitions in ISO 15065 must be taken into account. Table 9

14. Standard-height nuts with hexagon head When the switch from DIN standards to ISO standards took place, some nut heights were increased and the wrench sizes of sizes M10, M12, M14 and M22 were changed. The test forces were also increased and now have to comply with ISO 898-2 in the case of coarse threads and ISO 898-6 for fine threads. Nuts compliant with DIN 934 need only withstand the lower test forces of DIN 267-4. Nuts which do not exhibit full loadability pursuant to ISO 898 Part 2 or Part 6 on beams which cover the strength class marking on the nut, e.g. I8I, must be distinguished.

15. Flat-type hexagon nuts The DIN standards for flat nuts were retracted in favor of the ISO successor standards. DIN 439 Part 2 corresponded to ISO 4035 to a large degree, with the exception of the wrench sizes. Interchangeability is thus a given. DIN 936 was retracted without replacement, as only minimal demand still exists here. Nuts compliant with this standard have no defined thread test forces. We recommend testing the usability of the nuts pursuant to ISO 4035. Table 18

17. Hexagon nuts with clamping piece The DIN standards for hexagon nuts with a clamping piece (locking nuts) have been completely retracted and replaced with ISO successor standards. A large number of changes were made when the ISO standards were introduced. Note that, in the case of the successor standard to the frequently used DIN 985, i.e. ISO 10511, the strength classes were also changed. This is due to the fact that nuts of reduced loadability are concerned. Note, in particular, that nuts compliant with ISO standards may not be replaced with nuts compliant with the DIN standard should replacement be necessary. Table 22

23. Lock washers, tensioning washers and toothed washers The only DIN standard still applicable for setting locks is DIN 6796. All other DIN standards for these elements were retracted long ago. Testing showed the ineffectiveness of these products with screw connections greater than or equal to 8.8. DIN standard 6796 can be used as a setting lock in combination with screws up to and including strength class 10.9.

24. Cylindrical and tapered pins The DIN standards for cylindrical and tapered pins have all been retracted and replaced with EN or ISO standards. Some of the successor standards include length definitions different from the retracted DIN standards. Substitution of the DIN parts is usually possible without major structural intervention, however. For example, the nominal length definition for tapered pins as per DIN 1 and cylindrical pins as per DIN 7 is without points. In the case of successor standards EN 22339 and ISO 2338, the nominal length definition is for the entire length of the pin, i.e. including points and bevels. Table 29

25. Clamping pins The DIN standards for clamping pins/clamping sleeves have all been retracted and replaced with ISO successor standards. In the process, possible use in connections between clamping pins/clamping sleeves and screw connections found in some DIN standards was removed. In most cases, clamping pins compliant with DIN standards can be substituted with clamping pins compliant with ISO standards. Table 30 Interchangeability
