UNEFScrew Threads per ANSI B1.1. UNEF = Unified National Extra Fine. This is one of three graded series: UNC (Unified National Corase); UNF (Unified National Fine); and UNEF (Unified National Extra Fine). The Nominal Major Diameter and Threads-per-inch (Pitch) are defined by ANSI/ASME B1.1 and are the choices for the customary
MinorDiameter Formula. For a 60Ā° thread (ISO metric and Unified Inch standards), it equals to: D M i n o r = D N o m āˆ’ 5 8 Ɨ 3 Ɨ P. For example, for a UNC 1/4-20 screw, the nominal pitch diameter is: 0.25 āˆ’ 0.625 āˆ— 0.05 = 0.196 ā€ ( 4.98 m m) Determining the required Minor Diameter in each case is complicated and depends on the UNSUnified National Thread. UNS screw threads that have special combinations of diameter and pitch with tolerance to Unified formulation have the basic form designation set out first followed always by the limits of size. #10 - 1/4" 5/16" - 1/2" 9/16" - 1" 1 1/8"- 1 7/8" 2"- 2 1/2" 2 3/4" - 3 3/4" 4" - 6".

FineThread Series (UNF/UNRF) is commonly used in precision applications. Because of the larger tensile stress areas, they have high tension strength. However, a longer engagement is required for fine thread applications than for coarse series threads to prevent stripping. 3 ā„ 4 - 10: 0.6850: 0.302: 0.334: 3 ā„ 4 - 16:
