Pitch diameter Definition & Meaning - Merriam-Webster
WebPitch Diameter Formula The nominal value of the pitch diameter is a function of the pitch and the thread angle. For example, in a 60° thread (ISO metric and Unified Inch standards), it equals to: D P i t c h = D N o m − 3 8 × 3 × P For example, for a UNC 1/4-20 screw, the nominal pitch diameter is: 0.25 − 0.6495 ∗ 0.05 = 0.2175 ” ( 5.525 m m) WebThe lead angle of the thread depends on its pitch, the number of starts, and the diameter. Our threading calculator displays the lead angle based on these parameters. Tab #4– Over Wire Measurements (*) Measuring the pitch diameter becomes challenging when you machine a thread and don’t have the required Go/NoGo gauge. WebThe pitch diameter is the fundamental design geometry that determines the size shape and form of the sprocket teeth dimensions.
