Thread Shear Area Formulas and Calculator per. ASME B1.1
![](https://www.engineersedge.com/graphics/thrd-shear-area.png)
The following formulas for thread shear areas are geometric minimum values. Shear ( thread stripping) strengths of screw threads under load are dependent, in addition, on mating component relative material strengths, nut geometry, and coefficient of friction between thread bearing surfaces. Effective shear areas are therefore somewhat less than the geometric values. Equations and calculator per. ASME B1.1
