Letters closer to 'A' or 'a' indicate a large clearance. Letters near 'H'/'h' sit right on the nominal line. Letters moving toward 'Z' or 'z' create an interference (press) fit. 3. International Tolerance Grades / IT Grades (Numbers) din 7161 pdf

Most modern German engineering documentation has transitioned to . However, because millions of blueprints, legacy machines, and industrial tools were created under the older DIN system, cross-referencing DIN 7161 charts remains a day-to-day necessity in many machine shops worldwide.

For a ( 40 H7 ) hole:

Yes, for all new designs. However, for reverse-engineering a part made to DIN 7161, you should consult the original tables because the tolerance grade letters might have slightly different ranges, especially in the IT0 to IT5 range. Why Engineers Look for the DIN 7161 PDF

Some official platforms may still list the standard as a historic product for archival purchase.

These major global engineering document aggregators license standard sheets for commercial use.

DIN 7161 is a German standard developed by the Deutsches Institut für Normung (DIN) that defines the dimensional tolerances for plain cylindrical parts, such as shafts, holes, and cylindrical surfaces. The standard provides a set of rules and guidelines for specifying and verifying the dimensional accuracy of these parts.
