Amendments
The following amendments have been made to the October 1988 edition.
a)  For M3.5, M4 and M5 screws, k min values have been corrected.
b)  w min values have been amended.
c)  The mass given for M5 screws, 8mm long, has been amended.
d)  The standard has been editorially revised.

Explanatory notes
Most of the screw dimensions specified in this standard are the same as those specified in ISO 1207 (at present at the stage of draft), the only significant deviation that might impair their interchangeability being the head height, k, of screws smaller than M3 ISO heads are somewhat higher, which permits these heads to be used both for slotted and cross recessed head screws. A standard on the latter is in preparation. There are also slight differences with regard to dimension w min these being, however, of no significance for the user of this standard.
