WebMay 17, 2014 · Concentricity is a specific GD&T symbol. Coaxiality is not a symbol, nor is it a very specific term; it is a general word used to describe the idea of two or more circles that share a common center. The problem with that general word is that it leaves open the question of HOW to find the center of a given circle. WebGeometric tolerances include straightness, flatness, circularity and Cylindricity and orientations of shapes such as angularity, parallelism and perpendicularity. Run-out relates to radial features and reference axes and features that are 90 o to a reference axis.
