Thread Stripping BOLTCALC Thread stripping sometimes referred to as thread shearing is when the shear stress acting on the threads is such that the threads either shear completely so that the nut becomes detached or partially in which case the strength of the thread is severely impaired The program will determine the force to shear both the nut internal thread and the bolt external thread

that calculates shear areas for stubs acme s and V s but I have to run a virtual window to access it since it is 32 bit I may have to create a spreadsheet in the end but thought I would ask Thanks for any input or recommendations RE shear area Bolted Joint Design Fastenal fastener the total cross sectional area of the shear plane is important For shear planes through the threads we could use the thread root area There are two possibilities for applied shear load as illustrated below One possibility is that the shear plane occurs in the threaded portion of the bolt Since shear strength is

reduces due to the threads In fact there is a net area and a tension area which is slightly larger However choose the net area to be safe The shear area is the area of the bolt where no threads are
