WebMEASURING A FASTENER Shank Diameter Also called Major diameter. The diameter of a bolt is the Shank diameter, expressed in millimetres for Metric bolts. Because this is approximately the same as the Major or Thread diameter the thread diameter measurement can be used for fully threaded bolts. Shank Length WebFlatness means straightness in multiple dimensions, measured between the highest and lowest points on a surface. Circularity or roundness can be described as straightness bent into a circle. Cylindricity is basically flatness bent into a barrel. It includes straightness, roundness, and taper, which makes it expensive to inspect.
