🌀 3 4 16 Unf 2B Thread Dimensions

A3/8"-16UNC 2B is defined as a 3/8" diameter Unified coarse pitch 2B class of fit inch screw thread. If the thread is a 3/8"-16NC2 and the letters U, A and B do not appear in the thread designation, the thread conforms to the outdated American National thread. The Unified class of fit numbers have the opposite meaning of the Metric Screw

^{MinorDiameter Formula. For a 60° thread (ISO metric and Unified Inch standards), it equals to: D 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 on the} Threadgeometry for Unified Extra Fine (UNEF) threads.
