Their system is built with a spring ring and ball bearings on opposing flats, so when a nut or bolt is in the socket the ball bearings push out on the springs holding the nut or bolt in place

The joints are connected with mutually engaged hexahedrons, dispersing the load across the outer circumference for more durability and less wear-and-tear
