ISOFits calculates and displays limits and fits for shaft / hole combinations in accordance with the standards set forth in ISO 286-1:1988 and ISO 286-2:1988. Analyze known fits (what are the parameters of a 12 H5/d3 fit?), synthesize (find) the best possible fits given minimal input (I need a 25,4 mm basic size, shaft-basis, interference fit, with -25 um to -45 um clearance), view the three primary ISO 286 tables (standard IT tolerance, shaft and hole deviations), even scroll through a series of fits customized per your design rules.
