The part 1 of this standard specifies requirements for case hardened and tempered metric thread rolling screws with various forms of head geometry designed to produce internal threads with nominal diameters from 2 mm to 12 mm, which fit general purpose ISO metric screw threads and are used in general engineering applications. The form and arrangement of the screw section used for thread rolling shall be at the manufacturer's discretion. The length of this section shall not be below 1,5P and not exceed 4 P. This standard doesn't apply to thread cutting screws. DinEnIso 898-1 is not applicable to screws made with this norm.

(a) if screws with a shank are requested, according to DIN 962 the lenght of the thread is to be given in the designation e.g. DIN 7500 - OE M6 x 60 x 30
(b) if designatios do not include the sybol H or Z (to identify the cross recess), recess type H shall apply

The part 2 of this norm gives guide values for hole diameters for thread rolling screws DIN 7500-1 and DIN 267-30. The hole diameters are only guide values because they are assigned to different Materials and lenghts of engagement. Bigger hole diameters can be required, for example for special procedures. This norm doesn't apply to holes with special forms, for example triangular and octagonal holes.
