Swing bolts, also known as hinge bolts, live joint bolts or eye bolts, consist of a smooth, perforated spherical head and a threaded rod. One end is fixed at a pivot point, while the other end can swing freely into a locked position. When used together with a nut, swing bolts provide excellent holding strength. They are commonly used in mechanical equipment that requires quick fastening and releasing.
