Thread Measuring Wires (60-degree threads) - Calibration

Web25 jul. 2016 · BSPT & BSPP are NOT metric threads. British thread forms have a 55 degree flank angle and use sizes similar to our own pipe threads - 1/8, 1/4, 3/8, 1/2, etc. General practice is to use measuring wires of "best size," i.e., a wire that contacts at the pitch line. From the Machinery Handbook: Best wire size=0.5 pitch/cosA, where A = 1/2 … Web12 nov. 2024 · To measure the thread using this method you’ll need 3 wires and a micrometer.
