There is no positive tolerance on Head Diameter and no negative tolerance on Shank Length. Shank Length has a positive tolerance according to IT14 from ISO 286-2 (+0.25 to +0.62 depending on actual length). It is normal to have a radius under the head. DIN 660 is the same as BS 4620 Table 1, but with differing tolerances.
