The Britsh Standard does not specify tolerances for Head Diameter & Depth, Angle of Countersink,
Point Diameter & Depth or Shank Length.
It is normal to have a radius under the head and at the periphery of the countersink,
but no dimensions are specified.
*These Diameters are not specifically denoted in BS 641 Table 8.
