Both of these (nuts and bolts) are used to form a temporary hold between two or more different components. The simplest way of Torque measurement method.. 53 . 2. This means that a complete turn (360) of the spindle will produce an advance of twenty five thousandths of inch. A pair of anvils have external threads which match in pitch with the threads of the part. Threads produced to ASME B1.13M standard are fully interchangeable with threads that are based on ISO 68-1 basic profile and ISO 965-1 tolerance practices. The accuracy of the thread form of the screw determines the accuracy of the measurement. The screw thread micrometer reading indicates the thread pitch diameter. When the micrometer is zeroed, the pitch line of the spindle and anvil coincide. When the micrometer is used to measure the thread, it is measuring along the pitch diameter of the thread.
