External threads of this series have greater tensile stress area than comparable sizes of the Coarse series. 3.858: 2B: 3.962: 4.166: 4.31: 4.409: 4.826 #10 - 32UNF: 3A: 0: 4.826: 4.674 Measuredin Inches; Size Primary Inch Basic Major Diameter Inch Basic Pitch Diameter Inch Minor Diameter, inch Minor Dia. Area sq. inch Tensile Stress Area TheSpecial UNJ threads are designated by the nomenclature UNJS. J screw threads feature a root radius which improves the tensile stress area of the fastener and helps to reduce the stress concentration factor in the thread thus making the thread stronger. Additionally, the requirement for high strength is achieved with 3A and 3B classes of fit. UNJFThread Series, is suitable for the production of bolts, screws, and nuts for aerospace applications where the Root Radius is controlled. External threads of this series have greater tensile stress area than comparable sizes of the Coarse series. The Fine series is suitable when the resistance to stripping of both external.
