Metric threads are measured by the diameter of the threaded portion and by how far apart the threads are The common metric thread 10mm x 1 0 indicates a 10mm o d on the threaded portion and a thread pitch of 1 0mm which is one thread every millimeter Since there are 25 4 millimeters in 1 inch that works out to 25 4 threads per inch
