DIN439-1987分为两个部分，DIN439-1为无倒角薄螺母，DIN439-2为有倒角螺母，其中DIN439-2接近于国标GB6172.1螺母。实际应用场景中常见DIN439薄螺母为-2系列，即带倒角型。无倒角-2型几乎不常用，故在日常使用中常将DIN439默认为DIN439-2。

| 备注 | 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. | |||
