How is metric thread pitch measured
WebThe thread pitch can be determined by using gauges or by using known screws as gauges (even if they are different diameters). Hold the known screw against the one to be measured to see if it fits. A very slight mismatch means you are probably using the wrong measurement system. Metric instead of Imperial, or vice versa. WebISO metric thread H = 0.86603 P, H/4 = 0.21651 P, (3/8)H = 0.32476 P, (5/8)H = 0.54127 P, where P is the pitch of the thread. BS 3643–2 defines two series of diameters with graded pitches for general use in nuts, bolts and screwed fittings, one series with coarse and the other with fine pitches.
