... Fig. 12 ). If there are fits that need to be tight, as in press fits or locating fits, it is advisable to annotate the specification drawing as such, telling the toolmaker to stay on the “steel-safe” side of the tolerance zone during initial tool fabrication. In this manner, if the part needs to grow...
