ISO-fits for the hole basic system; tolerances of fit (clearances and interferences)doi:DIN 7154-2
However, in addition to these tolerances the class of fit may be specified. There are two bases for systems of limits and fits and these are (Simmons and Maguire, 2001): Hole basis – in this system the shaft must fit the hole. This means the hole size remains constant while the shaft...

I tested eight double-sided boards for two hole sizes: 0.125 inch and 0.29 inch. I conclude that all of these manufacturers met the tolerances specified. You should anticipate variances of at least ± 0.003 in PCB hole sizes. In the above table, notice one board is listed as “silver has...
Press-fit holesare placed in holes with a tolerance stricter than the +/-0,10mm norm. Thepress-fit hole sizefits the connection leads, which are not soldered and forced into the hole. Thetolerancesare highly specified and tighter than the norm to permit the result and hole to precisely fi...
(due to process tolerances). So your mileage may vary. On the 741 of the above schematic I measured an output swing from -2.84V to +4.5V, but in my PC48 Apple II clone I measured -2.82V to +4.54V, similar enough. In a real Apple IIe I measured an output swing of -3.16V to ...
Geometrical tolerances are assigned in addition to the dimensional tolerances whereas, for certain applications, the latter may also include some provision for them. Maximum and minimum functional clearances, dimensional and geometrical tolerances of a peg-and-hole assembly consist of a system where ...
The difference between the two diameters is greater than the possible oval distortion of the hole and takes into account fabrication tolerances so as to ensure permanent contact between the protrusions (4) and the hole wall in all case of load and overload. Axial fixing in the hole is ...
