About Projected Tolerance Zones

Projected tolerances are used to make the tolerance more specific.

Projected tolerances are specified in addition to positional tolerances to make the
tolerance more specific. For example, projected tolerances control the perpendicularity
tolerance zone of an embedded part.

The symbol for projected tolerance ( ) is preceded by a height value, which specifies
the minimum projected tolerance zone. The projected tolerance zone height and symbol
appear in a frame below the feature control frame, as shown in the following illustration.

spSep 2010 The projected tolerance is a GD&T modifier used for threaded and press fit holes in order to ensure the proper fitments of the mating parts by means of studs or bolts.
