The tourque-shear (T.S) bolt method is a method of evaluating that when a designated amount of torque is applied to the bolt, the pintail at the end of the bolt is broken, and the fastening tension at this time has reached the target standard bolt tension. It has advantages in terms of convenience and reliability as it can minimize deviations depending on the operator's skill level and maintain clamping force in bolt fastening parts. However, T.S bolts must be fastened using a dedicated equipment called a shear wrench, and there are disadvantages in inventory handling and cost as T.S bolts of different sizes must be provided depending on the fastening thickness of the joint. Accordingly, this study aims to develop the T.S nut method, which maintains the advantages of T.S bolts and complements the defects.
