  • Patent number: 4570987
    Abstract: The invention involves a swivel eyebolt of the type which relies on a threaded stud to anchor a bonnet and accompanying ring to a load allowing the bonnet 360.degree. or rotation. Of special consequence is the structure which features a bushing applied around the exposed part of the stud and held in place by the head of the stud so that a flange on the bushing engages the load. The bonnet in turn is clamped rotatably on the bushing so that the bonnet in fact rotates about the bushing as well as about the stud.
