Limits of sizes for metric coarse thread
This table contains information on limits of sizes for metric screw thread, coarse series, fit 6H/6g.
values in mm
1) The values for sizes 1 up to and
including 1.4 mm correspond to the fit 5H/6h.
2) Metric screw thread is designated by the basic diameter, preceded by
the profile letter M and followed by the tolerance grade, e.g. 6, and the
tolerance position, e.g. g. Example: M10 - 6g. If no tolerance class is indicated
the above mentioned fits are valid.
For coated threads the maximum values of d, d2 and d3 are equal to the values of the basic profile (d2max = D2min and d3max = D1min).
