WebA generally used practical calculation method for the tread stripping strength is given by the formula A th =0.5πd 0 L 0. where d 0 = (d 2 +d 3 )/2. Applying this formula results in the effective length of thread engagement of L 0 =11.5mm. Note that the shear strength of a metric fine thread exceeds that of a standard metric thread because of ...
