WebbStep 1. Read the first letter of the size. This the largest diameter: the measurement of the screw on the thread. Unified screw diameters are measured in inches -- lowest to highest as 0 to 10. Measurements equal 0.060" + 0.013" x measured diameter. Video of the Day. For example: 4-30 x .10 has a major diameter of 0.112". WebbScaling the cosine to thread dimensions. When drawing the 2D elevation of a screw thread, the thread crest cosine function must be scaled horizontally to match the thread pitch and vertically the thread crest or root diameter. If pitch = P P then X coordinate scale factor, sp sp, must map 2\pi 2π to P P, hence sp = P/2\pi sp = P /2π .
