WebAnchor Bolts. Donald M. Harrison, in The Grouting Handbook, 2013 Thread Deformation. Plastic flow and stress will occur in thread roots and in the first few bolt threads that engage the nut threads. An old rule of thumb was that for every 10,000 lb of stress applied to a bolting mechanism, the load was picked up by an additional thread. An example of this … WebUNJ bolts are like UNR, but the curve of the thread root is gentler which requires that it be shallower. In fact, the thread root is so shallow that the bolt thread cannot mate with a … WebThe difficulty lies in determining the cross sectional area in which the shear will occur. Here are three possible scenarios for this type of failure. 1. The nut material is stronger than the bolt material. In this example, the nut threads will shear out the bolt threads. The failure will occur at the root of the bolt threads. 2. sweatband trustpilot
