Metric thread size and tolerance calculator was developed to calculate major, minor and pitch diameters of the external (bolt) and internal (nut) metric threads according to ISO 724:1993 standard. In addition to basic size calculations of metric threads, tolerance calculations of different tolerance classes can be done according to ISO 965-1:1998 and ISO 965-2:1998 standards. There are two calculation options available, general engineering use or custom use. In general engineering use, calculations can be done by selecting a standard metric thread size from the list which contains metric thread sizes in the diameter range from 1.6 mm (M1.6) to 64 mm (M64). Tolerance class can be selected among the alternatives 6e, 6f, 6g and 4h for bolts and 5H, 6H, 7H and 6G for nuts.

6g and 6H are default values and selected class for commercial external threads and internal threads in ISO 965-1:1998. The user shall use 6g for bolts and 6H for nuts unless there is a specific requirement to use other tolerance classes.

In custom use, thread size, pitch and tolerance classes can be independently selected for custom engineering calculations. Some important notes from ISO metric screw threads standards: - External Screw Thread Designation: Nominal Diameter x Pitch - Tolerance class for pitch diameter - Tolerance class for major diameter (M10 x 1 5g 6g) - Internal Screw Thread Designation: – Nominal Diameter x Pitch - Tolerance class for pitch diameter - Tolerance class for minor diameter (M10 x 1 5H 6H) - If the two class designations for the pitch diameter and crest diameter are the same it is not necessary to repeat the symbols. (M10 x 1 6g) - According to ISO 1:2002, standard reference temperature for geometrical product specification is 20 °C. - Gauges and gauging for ISO general purpose metric threads are defined in the ISO 1502:1996 standard. - The basic profile of ISO general purpose metric screw threads is defined in the ISO 68-1:1998 and given in the first figure below. External (bolt) thread root profile is given the 'Definitions' section. The list of metric screw thread used in general engineering applications are given in the.

Thread standards Tapping tools are manufactured in five different standard: ISO, ANSI, DIN, DIN/ANSI and JIS. DIN and ISO are common world-wide, ANSI is most common in American markets and JIS is most common in Asia markets. • ISO, ANSI and JIS have quite short OAL (overall length) and are rather similar, except for the shank diameter which is in inch for ANSI and metric for ISO and JIS • DIN is a long version, with metric shank diameter and long OAL • DIN/ANSI is a mix of both, with ANSI shank diameter and OAL from DIN.
