Limits of sizes for metric fine thread according to ISO 965 part 2

This table contains information on limits of sizes for metric screw thread, fine series, fit 6H/6g.

values in mm

Metric screw thread, fine series, is designated by the basic diameter, preceded by the profile letter M and followed by the pitch separated by an x-mark and then by the tolerance grade, e.g. 6, and the tolerance position, e.g. H. Example: M10 x 1.25 - 6H. If no tolerance class is indicated the fit 6H/6g is valid.

For coated threads the maximum values of d, d₂ and d₃ are equal to the values of the basic profile (d_2max = D_2min and d_3max = D_1min).
