If, in special cases, nuts are to comply with specifications other than those given in this standard, e.g. regarding materials other than those specified in DIN 267 Part 15, resistance to corrosion, high temperature strength over+ 120 °C, or the like, these shall be the subject of particular agreement at the time of ordering (see also "Field of application" clause in DIN 267 Part 15).
