① Only for screws without surface protection. 6 g makes it possible for normal coating thicknesses to be applied in accordance with DIN 267 part 9, the reference line not being exceeded. Depending on the coating thickness required, a larger fundamental deviation shall be selected than that for the g position. This might, however, impair the resistance to stripping of the bolt / nut assembly.
