Referto the table for dimensions of commonly used bolt sizes. Measurements on top row represent UNC threads and measurements on bottom row represent UNF threads. Class 2A is acceptable for the majority of applications and Unified Thread Standard (UTS) bolt classes. 24. 2A. 0.3114. 0.3042. 0.2843. 0.2806. 0.2603. 3/8. 16. 2A. 0.3737. 0.3643
ExternalThread. Designation: d. The major diameter is measured on the crest of the thread. The major diameter is a critical dimension to control. Together with the pitch diameter, it forms the addendum of the thread and controls if the screw would fit on a bolt. The permissible range for the major diameter is derived from its class.
UNFThread Series / UNRF, is suitable for the production of bolts, screws, and nuts and for other applications where the Coarse series is not applicable. External threads of this series have greater tensile stress area than comparable sizes of the Coarse series. 1 1/8" - 12UNF: 2A: 0.0018: 28.529: 28.24. . . 27.155: 27.003: 26.01: 2B: 26.
