ASME/ANSI B18.3-2002
  • U.N.C.: Acronym, Unified National Coarse. The most common thread type of the Unified Thread System (U.N.C. - U.N.F. - U.N.S. - etc.), and is the preferred thread type for general purpose inch fasteners. Because of the coarse pitch, the threads are deeper than finde threads (U.N.F.) and are easier to assemble without cross threading.
  • U.N.F. : Acronym, Unified National Fine. A thread type of the Unified Thread System (U.N.C. - U.N.F. - U.N.S. - etc.) that has a slightly higher breaking load capacity than U.N.C. (Unified National Coarse) threads. This higher breaking load capacity is a result of the more shallow thread depth and larger tensile stress area for fasteners of the same identical material and diameter. The smaller lead angle allows for fine adjustments where needed.
