DIN439-1987分為兩個部分，DIN439-1為無倒角薄螺母，DIN439-2為有倒角螺母，其中DIN439-2接近于國標GB6172.1螺母。實際應用場景中常見DIN439薄螺母為-2系列，即帶倒角型。無倒角-2型幾乎不常用，故在日常使用中常將DIN439默認為DIN439-2。

| 備注 | ① Where a protective coating is applied e.g. an electroplated coating comflying with DIN 267 part 9, depending on the coating thickness required, it may be necessary, particularly in the case of tolerance class 6H nuts, to select a larger fundamental deviation than that assigned to the H position (see DIN 267 part 9 ). This, however, might impair the resistance of the bolt / nut assembly to stripping. | |||
