| 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. | |||
