WebMeasuring Bolt Dimensions & Diameters. The size of a bolt is determined by the diameter of the bolt’s shank (separate from the bolt head). Bolt diameter is typically separated into three categories: Major diameter: The largest and most outer diameter of a bolt’s shank. Pitch diameter: The diameter where the thread thickness = the space ... WebD M i n o r = D N o m − 5 8 × 3 × P For example, for a UNC 1/4-20 screw, the nominal pitch diameter is: 0.25 − 0.625 ∗ 0.05 = 0.196 ” ( 4.98 m m) Determining the required Minor Diameter in each case is complicated and depends …
