    Standard ISO 4759/1/DIN ISO 4759 Part 1
    Surface finish Black oxide (thermal or chemical)
    DIN 267 Part 2 shall apply with regard to surface roughness.
    DIN 267 Part 19 shall apply with regard to the permissable surface defects.
    DIN 267 Part 9 shall apply with regard to electroplating.
    If different electroplating or other surface protection is desired, this shall be agreed upn at the time of ordering
    Acceptable inspection DIN 267 Part 5 shall apply with regard to acceptance testing.
    a   Only for screws without surface protection, 6g makes it possible for normal coating thicknesses to be applied in accordance with DIN 267 Part 9 but the reference line shall not be exceeded. Depending on the coating thickness required, a larger fundamental deviation shall be selected that for the g position. A larger fundamental deviation may impair the stripping strength of the screw/nut connection.
