ANSI Socket Head Screw Engineering Dimensional Data Table Chart per ASME / ANSI B18.3 and ASTM A574. All dimensional data is given in inches.

The M3 and M4 nominal screw sizes have two drilled holes spaced 180 degrees apart. Nominal screw sizes M5 and larger have six drilled holes spaced 60 degrees apart unless the purchaser specifies two drilled holes.

ISO 4762 specifies the characteristics of hexagon socket head cap screws with coarse pitch thread from M1,6 up to and including M64 and product grade A.

For knurled screws the maximum head diameter shall be measured across the tops of the knurl and the minimum head diameter shall be the diameter of the un-knurled portion, or the diameter across the tops of the knurl for those screws not having an un-knurled portion, just above the radius or chamfer at the bottom edge of the head. Head Chamfer.

Sockets. Sockets, also known as socket cap, socket head, or socket screws, are a type of threaded fastener and cap screw that have sockets in their head through which torque is applied to screw the fastener. Depending on the type of socket head, a certain tool is required to fasten the screw in place such as a screw driver or Allen wrench.
