WebBolted Joint Systems Engineering standards for reliable, safe bolted fastening systems exposed to fluctuating loads require both adequate bolt torque to provide joint preload and the provision of a secondary locking feature. This is done either by lock-wire or some other means of developing fastener running torque that will resist bolt rotation. WebA bolted joint is most commonly preloaded, or prestressed, through the initial torquing of the joining elements. When an external torque is applied to the system, the bolt is elongated and the abutments (flanges) are …
