The limit dimensions for standard threads given in the table correspond to the - tolerance field 6g for bolt threads - tolerance field 6H for nut threads. The metric steel / metal threads specified in this catalog are based on these tolerance fields.

The basic dimensions are nominal dimensions of a metric thread profile without allowance and tolerances (The thread class defines that). They are based on standard ISO 68-1. The basic dimensions can be used for design.
The metric ISO standard thread is standardized according to the DIN 13-1 standard, which covers standard threads with an outer diameter of 1 to 68 mm. This standard was first defined back in 1949, but has been revised and updated many times since then.
