WebAug 24, 2014 · In English measurement threads have two numbers to describe them: 1) The nominal diameter. 2) The number of thread turns in each inch. 1/4 = .250 inch. 20 = 20 turns to advance the thread one inch. The pitch is 1/20 inch per turn = .05 inch. Metric thread usually use (you know this, for comparison) 1) Nominal diameter. 2) thread pitch.
