Web4. Bolt Overload. Bolt overload is a result of the applied force being sufficiently high, causing the bolt to fail due to overload, which is a direct result of the axial force being applied acting upon the bolted joint, which then causes the bolt to fracture in the threaded area. 5. Excessive Bearing Stress.
