Calibration may also be given in lbf.in and lbf.ft. 3. The uncertainty quoted is for the departure from flatness, straightness, or squareness, ie the distance separating the two parallel planes which just enclose the surface under consideration Single start, symmetrical thread forms only. 5. Single and multi-start, symmetrical thread forms only mm to 3 mm diameter range relates to functional test of size using check plugs.
