Sechskantschrauben mit Gewinde bis Kopf; Gewinde M1,6 This standard, together with

bis M52; Produktklassen A und B DIN (SO 4017, September 1987 edition,

supersedes the December 1983 edition This standard should be used together with {SO 4017 For details, see Explanatory notes It is intended to withdraw the present standard by 1 July 1992 at the latest,

In keeping with current practice in standards published by the international Organization for Standardization (ISO), acomma has been used throughout as the decimal marker

Dimensions in mm

1 Field of application

This standard specifies requirements for M 1,6 to M 52 hexagon head screws threaded up to the head, assigned to product grade A, for sizes up to M 24 and lengths not exceeding 10 d or 150 mm, and to product grade B for sizes greater than M24

or Jengths exceeding 10d or 150mm

The screws are designed similar to those specified in DIN 931 Part 1, but are threaded up to the head and have com-

mercial lengths up to and including 200mm

If, in special cases, screws are to comply with specifications other than those given in this standard, e.g regarding property class, these shall be selected in accordance with the appropriate standards
