• Engineering Fundamentals of Threaded Fastener Design and ...

    The basic torque distribution for a fastener is illustrated in Figure 4. The torque applied to a fastener is absorbed in three main areas. First, there is underhead friction, which may absorb 50 percent or more of the total torque. Thread friction absorbs as much as 40 percent of the applied torque.
