The surface at the bottom of the groove connecting the adjacent flanks. Internal thread minimum pitch diameter [D 2min ].

In addition to basic size calculations of metric threads, tolerance calculations of different iso 965-1 classes can be done according to ISO The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions and angles common to internal iso 965-1 external threads.

External thread maximum pitch diameter [d 2max ].

Use this tolerance class for commercial internal threads. External thread maximum major diameter [d max ]. Tolerance class can be selected among the alternatives 6e, 6f, 6g and 4h for bolts and 5H, 6H, 7H and 6G iso 965-1 nuts. Internal thread maximum iso 965-1 diameter [D 2max ]. AmesWeb Calculators Screw Threads. Tolerance Class 95-1 Bolt. General Engineering Use Custom Use. The surface at the top of the ridge connecting its two flanks.

The user shall use 6g for bolts and 6H for iso 965-1 unless there is a specific requirement to use other sio classes. After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H. Internal thread minimum minor diameter [D 1min ]. Internal thread minimum major diameter [D min iso 965-1. In general engineering use, calculations can be done by selecting a standard metric thread size from the list which contains metric iso 965-1 sizes in the diameter range from 1.
