UNIFIED THREAD STANDARDS
Thread standards agreed upon by standard bodies of Canada, the United Kingdom, and the United States.
Unified National (UN)thread form with a rounded root contour, applies only to external threads. (The UN thread form has a flat, or optionally, a rounded root contour.) The majority of fasteners with a Unified thread form (UNC, UNF) have a rounded root contour i.e. are UNR threads.
Unified National Fine (UNF)is a thread form with a 60 degree flank angle rounded roots and flat crests. For a given diameter it has a smaller thread pitch than an equivalent diameter UNC thread.
