Now, let's address the "extra quality" part of your keyword. When dealing with a withdrawn technical standard, it's important to understand what a "quality" PDF means.

To correctly utilize a DIN 7161 reference layout, follow these steps:

[Clearance Fit] --> Components move or rotate freely (e.g., shafts in bearings). [Transition Fit] --> Components may require light pressure or tapping to assemble. [Interference Fit] --> Components are tightly locked together (e.g., press-fits). Clearance Fits (e.g., H7/g6) : The hole is always larger than the shaft.

Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 1: Basis of tolerances, deviations and fits.

No blurry text, faded lines, or missing numbers.
