There is no negative tolerance on Head Depth and Shank Length.
There is a positive tolerance on Head Diameter.
Shank Length has a positive tolerance (ranging +0.7 to +1.6) depending on actual length.
It is normal to have a radius under the head.
DIN 124 is the same as BS 4620 Table 2, but with differing tolerances.
* This Diameter is not specifically denoted in DIN124.
