Patent ID: 8752455

Claim:
A mechanical arrangement for electrically, hydraulically, or pneumatically tightening, loosening or removing nuts and bolts of various sizes, the mechanical arrangement comprising: a socket driver configured to receive and to be rotatively driven by a torque force from at least one of electrical, hydraulic, or pneumatic means, wherein the torque force generated by the electrical, hydraulic or pneumatic means is greater than 1,000 foot pounds; a plurality of hollow-shaped socket insert adapters that are configured to be rotatively driven by the socket driver, and to receive the electrical, hydraulic, or pneumatic torque force via the socket driver, for tightening, loosening, or removing the nuts and bolts of various sizes, a given one hollow-shaped socket insert adapter of the plurality of hollow-shaped socket insert adapters comprising: an outer configuration that has a shape and a size to conform to and to fit into a cavity of a socket driver body of the socket driver; an inner configuration that: has a shape and size to conform to and to fit on a head portion, having outside corners, of a given nut or bolt to be driven and wherein the shape of the inner configuration is a closed hollow shape; and includes at least four or more inner flat walls and four or more rounded inner corners, the inner configuration being shaped to allow the at least four or more inner flat walls of the inner configuration to contact and engage, and the four or more rounded inner corners to avoid contacting and engaging, the outside corners of the head portion of the given nut or bolt to be driven; wherein the flat walls and rounded inner corners increase the ability of the plurality of hollow-shaped socket insert adapters to receive the electrical, hydraulic, or pneumatic torque force via the socket driver and to transmit the torque force to the given nut or bolt to be driven; and wherein the outer configuration defining four or more outer flat walls that intersect to define a multi-sided closed polygonal shape, the intersections of the four or more outer flat walls defining four or more non-protruding rounded outer corners that do not protrude beyond the intersections of the outer flat walls, the outer configuration being shaped to allow the four or more outer flat walls of the outer configuration to contact and engage, and the four or more non-protruding rounded outer corners to avoid contacting and engaging, one or more inner walls defining the cavity of the socket driver body of the socket driver, wherein at least the four or more non-protruding rounded outer corners of the outer configuration configure the outer configuration to fit into and to receive torque at least via a socket driver cavity that does not include rounded inner corners.
