8 Ιαν 1993 · The nominal diameter d is specified in mm as part of the bolt designation, e.g. 8 mm for M8 bolt. The standard metric bolt diameters are specified in the standard ISO 898-1 Tables 4 and 5. For typical coarse pitch thread bolts the standard sizes are: M3, M3.5, M4, M5, M6, M7, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30, M33, M36, M39.

Calculate external and internal metric thread dimensions including major diameter, minor diameter, pitch diameter and thread tolerance according to ISO 724 and ISO 965 standards.
The Metric thread standard ISO 965-2 provides the limits only for classes 6H & 6g*. In all other cases, calculations must be made manually according to the below formulas or by our Threading Calculator. * For threads over 1.4 mm and classes 5H & 6h for threads up to and including 1.4 mm.
ISO 724 specifies basic dimensions of metric threads in accordance with ISO 261. Dimensions refer to the basic profile in accordance with ISO 68. The pitch varies from coarse to extra fine with up to 5 different pitches for some dimensions. The thread angle is 60 o and the thread depth is 0.614 x pitch.
