Evaluate limits and fits for a pair of –diameter 6 h7 g6 solution: the size 6 mm lies in the diametral step of 3 6, therefore, d is given by – the value of fundamental tolerance unit is given by – limits of tolerance for hole h7 the standard tolerance is –16 i = 16x0.7327 = 11.72 = 12 µm the fundamental deviation h hole is –0. Limits, fits and tolerances. m m. due to the inevitable inaccuracy of manufacturing methods, a part cannot be made precisely to a given dimension. the permissible variation on the size is called tolerance. the two extreme permissible sizes on the actual size are called limits. when two parts are to be assembled, the relation resulting from the. 1.unilateral tolerances: if the variation permitted is at only one side of the given dimension, called unilateral tolerance. when the variation permitted is at only one side of the given dimension, then it is slightly difficult to manufacture the components. hence the cost of manufacturing will be high. ex: mating parts.
