HB-302 Thread Measurement

The Thread Measurement handbook consists of 267 pages and covers the measurement and gaging of screw threads: the geometry and terminology of straight and tapered threads, the Unified inch, ISO metric, and pipe-thread systems and their designations, the fits and tolerances that make threads interchangeable, the functional gages and variable methods used to inspect them, the thread measuring wires and setting gages that stand behind those methods, the calibration of wires and gages, and the uncertainty, care, and reporting that make a thread result defensible.
