WebFlatness description: flat within 0.005” per foot Parallelism description: parallel within 0.005” Thickness, Parallelism and Flatness – Definitions Plate thickness: the distance between two surfaces of a part (commonly the top and bottom) with a deviation tolerance specified (ex. 2.307” +/-0.0010”). Web3.4 LOCATION - Position tolerances are the most common location tolerance. Concentricity and symmetry are also types of location tolerances. Profile tolerances can be used to control location, but these are covered separately. 3.4.1 Position - The position tolerance symbol is a circle with a horizontal and vertical line drawn through the circle.
