1) Whichever is shorter(see steeped line in the dimension table)
2) Only for screws without surface protection. 6g makes it possible for normal coating thickness to be applied in accordance with DIN267 Part9, 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, might resistance to stripping of the bolt/nut assembly.
