Scope and field of application

This standard supplements DIN ISO 4759 Part 1 and applies to those product standards (dimensional standards) in which DIN 267 Part 2 is referred to, e.g. with regard to the surface roughness of bolts, screws and nuts.

Note. The illustrations providing information on the tolerances, which were included in the April 1968 edition of DIN 267 Part 2, have to a large extent been replaced by the specifications given in ISO 4759 Part 1. In this standard, only individual characteristics of fasteners, e.g. bolt lengths, have been toleranced, so that the individual product types are not illustrated, or are only shown in part. To simplify the use of both these standards, the previous illustrations have been assembled in Supplement 1 to DIN 267 Part 2.

In cases of doubt, the specifications given in the product standard or in ISO 4759 Part 1 and in this standard shall apply.

It is recommended that Standards ISO 4759 Part 1 and DIN 267 Part 2 should also be used for nonstandardized fasteners and that these standards should be referred to giving details of the respective product grade in the purchase order documents.
