External thread maximum truncation [C max ]. The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table.

Details for the manufacture iso 965-1 use of gauges for checking ISO general-purpose metric screw threads are specified in the ISO The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions 95-1 angles common to internal and external threads. In general engineering use, calculations can be done by selecting iso 965-1 standard metric thread size from the iso 965-1 which contains metric thread iso 965-1 in the diameter range from 1. Tolerance class can be selected among the alternatives is, 6f, 6g and 4h for bolts and 5H, 6H, 7H and 6G for nuts.
