Thedifference between class 2A and 3A external threads is shown for 5/8-18 UNF parts. Note that for class 2A, both the major and pitch diameter maximums are below their respective basic values by the 0.0014 inch allowance. The allowance is 30% of the class 2A tolerance. For class 3A, the major and pitch diameter maximums are at the

ASME B1.1 1989 Unified Inch Screw Threads Relationship between the tolerances mm to ins. / 25,4 Tolerance class ins. to mm x 25,4 2A is the foundation 1A = 1,500 x 2A 2A = 1,000 3A = 0,750 x 2A 1B = 1,950 x 2A 2B = 1,300 x 2A 3B = 0,975 x 2A Example :
InApril 1955, representatives from the UK, Canada and the USA agreed on a miniature thread standard. The measurements for the Unified Miniature thread has been defined with reference to the ISO standard. Unlike most metric Screws, the designation consists of the diameter of the screw in millimeters followed by UNM. The flank angle is 60°.
Overview The Unified Thread Standard (UTS) defines a 60° thread form in Inch dimensions as described in the ASME B1.1 standard. It is the North American
