The DIN Standard does not specify tolerances for Head Depth, Angle of Countersink,
or Point Depth & Diameter.
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
(+0.3 to +0.52 depending on actual length).
It is normal to have a radius under the head and at the periphery of the countersink,
but no dimensions are specified.
* This dimension taken from DIN 675 may be incorrect.
DIN 675 is very similar to BS641 Table 8, but with more exceptional tolerances
and slightly altered Point dimensions.
