To measure an NPSM (National Pipe Straight Mechanical) thread, you need to use a thread gauge specifically designed for NPSM threads to check the pitch and diameter. Ensure that the gauge fits snugly without gaps or overlaps, and use a caliper to measure the outside diameter of the male thread or the inside diameter of the female thread to confirm it matches the specified NPSM dimensions.
