    Thread Pitch
    Here a simple method to check the thread pitch of your axle with a normal vernier caliper.
    Measure the total width of 4 thread "roots" as follows:
    • Align caliper "jaws" with the "first" and with the "fifth" crests (4 roots).
    • Total width 4mm --> thread pitch 1mm
    • Total width 5mm --> thread pitch 1.25mm
    • Total width 6mm --> thread pitch 1.5mm
