How is straightness measured
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 WebCylindricity, which regulates the deviation from the geometrically perfect cylinder, is measured using a roundness measuring instrument or a coordinate measuring machine. This page explains how to do this, as well as the advantages and disadvantages of using these instruments. “Learning GD&T From Scratch,” provided by KEYENCE, walks you …
