USS is about 20 ksi (138 MPa) PDmin is 2.675 mm Engagement is much less than 4.5mm if you count chamfers on both the screw and hole and incomplete threads. Helix area is less than 50% but I can't quickly find the means to calculate the exact figure (don't know your tolerance anyway). WebNov 5, 2008 · A = K*Pi*D*T where D is the thread minor diameter, Pi = 3.14, T is the thread engagement, and K is a function of the internal thread contact, which in worst case is 0.5 for square threads. Set stress equal to shear yield stress and solve for force, P. But do it right! Nov 5, 2008. #3.
