WebJun 3, 2004 · If a bolt (or screw) is to shear, it will fail across the thread. Just use this area in the general equation: in your case, just assume the load is acting across the cross section of the root of the thread, and devide the load by that area. The max shear loads can be found in the back of most bolt/screw producers catalogues. WebCase 2. The bolt material is weaker in shear than the nut material. The failure will occur along surface B in the figure above. The shear area is generally taken to be Ad ts ≈π()0.75 , where t is the nut thickness and d is the major diameter.
