UNC Thread Chart
The Unified Thread Standars (UTS) defines a standard thread form and series along with allowances, tolerances and designations for screw threads, commonly used in energy, petrochemical and offshore industries. It is the main standard for bolts, nuts and other threaded fasteners.
- UNC – Unified National Coarse thread. has the same 60° profile as the ISO metric screw thread, but the dimensions of the outer diameter were choses as an inch value.
- UNF – Unified National Fine thread.
| Diameter size | Thread Form & Pitch |
| 5/16” | 18 UNC |
| 3/8” | 16 UNC |
| 7/16” | 14 UNC |
| 1/2” | 13 UNC |
| 5/8” | 11 UNC |
| 3/4” | 10 UNC |
| 7/8” | 9 UNC |
| 1” | 8 UN |
| Bigger than 1″ | 8 UN |
