The main functions of twist shear bolts include anti loosening, anti over tightening, and reusability. Twisted shear bolts will undergo elastic deformation during the fastening process, forming a fixed locking structure in the internal fracture area, thereby preventing the fastener from loosening due to vibration or other external forces.

In addition, the twist shear bolt only requires a certain amount of torque to be applied during the locking process, which can effectively prevent damage to the fastener caused by over tightening, and can be repeatedly used without losing the locking function due to over tightening.
