1、DEUTSCHE NORM February 1995 Hexagon set screws with small hexagon, half dog point and flat cone point DIN 564 ICs 21.060.10 Descriptors: Fasteners, screws, set screws. Sechskantschrauben mit Ansatzspitze und kleinem Sechskant In keeping with current practice in standards published by the Internation

2、al Organization for Standardization (ISO), a comma has been used throughout as the decimal marker. Supersedes February 1985 edition. Dimensions in mm 1 This standard specifies dimensions and technical delivery conditions for coarse and fine pitch thread M6 to M36 hexagon set screws with small hexago

3、n, half dog point and flat cone point, assigned to product grade A. These screws are only to be used as forcing screws (.e. for adjusting and locating purposes when there is considerable resistance to motion). NOTE: For sizes M12 and M16 screws, this standard specifies widths across flats which are

4、in current use, .e. 16 mm and 18 mm, in accordance with IS0 272. Specifications for obsolete widths across flats (17 mm and 19 mm) are pro- vided in Appendix A. Where screws are to comply with specifications other than those given in this standard (e.g. regarding nominal length or property class), t

5、hese shall be selected in accordance with the relevant standards.
