DIN 7161 provides a standardized "vocabulary" for how two parts—typically a hole and a shaft—should fit together. It defines the specific tolerances din 7161 pdf
While is a withdrawn standard, it represents a critical piece of engineering history and standardization logic. It simplified the drawing process by establishing default "acceptable error" ranges based on machining capability. For modern applications, engineers should refer to ISO 2768-1 , but a solid understanding of DIN 7161 remains necessary for interpreting archives of German engineering drawings. : It remains one of the clearest examples
