An adjustable socket assembly includes a collet having a first end, a second end, and a perimeter wall. The second end has a receiving aperture therein. The collet is divided into a plurality of sections. A sleeve has a bottom end that receives the collet. The sleeve has an interior surface that tapers inwardly and abuts the sections to move toward each other as the sleeve moves toward the second ends of the sections. A biasing member extends through a top end of the sleeve and engages each of the sections. The biasing member is actuated to bias the sleeve downward to close together the sections and engaged the valve actuator. An engagement head is attached to the upper end of the biasing member and engages a tool to rotate the collet.

An apparatus for applying torque to a body includes a base defining an inner chamber. The apparatus includes a plurality of pins supported by base and disposed in the inner chamber, the plurality of pins moveable relative to the base between engaged positions and disengaged positions. The apparatus includes a trigger actuatable to move at least one of the plurality of pins to the disengaged position.

A tool for engaging drive flanks of a threaded nut has a tool body with a central cavity. Cam surfaces are formed in an inner wall of the central cavity. A retainer secured within the central cavity has an outward-facing slot. A jaw for each of the cam surfaces has a curved outer side in contact with one of the cam surfaces and a drive surface on an inner side for engaging one of the drive flanks of the nut. A foot extends inward from a lower end of each of the jaws into the slot to retain the jaws within the central cavity. Rotating the tool body relative to the jaws moves the drive surfaces of the jaws from a retracted position to a gripping position in engagement with the drive flanks of the nut.

A tension lever includes an outer body including a top, a bottom, and a plurality of outer body sides including a first outer body side and a second outer body side opposite to and facing the first outer body side, the first outer body side having a substantially planar surface extending along a first direction and a second direction crossing the first direction, an upper first opening defined in the top and defining an upper inner body that extends along the second direction, a lower first opening defined in the bottom and defining a lower inner body that extends along the second direction, a second opening defined in the first outer body side and the second outer body side, the second opening defining a channel that extends along a third direction crossing the second direction, and a barbell including a shaft and a pair of beads at opposing ends of the shaft, the barbell being received in the second opening.

A self-adjusting-size socket formed as a pair of coaxial tubes in rotatable relationship to one another, the innermost tube having a limited directional distance and independently rotational relationship with the outer tube by rotating along a mated set of threaded structures on immediately adjacent sides of the coaxial pair of tubes. The inner tube is a deep well chamber having a tool receiving end and a fastener receiving end, with an annular array of independently pivotable fingers arranged about an internal perimeter of the inner tube at the fastener receiving end. Rotation of the inner tube pushes a lowermost portion of the inner tube against the fingers, pushing them into the deep well chamber and around an irregularly shaped bolt or nut style fastener, gripping the fastener and allowing a user to remove or reinstall the fastener. The fingers self-adjust around the fastener.

A self-clamping torque adapter comprises a tool base, a central hub, a plurality of clamps, and a cam actuator mechanism. The tool base has a central axis and the central hub is rotatably coupled to the tool base and configured to rotate relative to the tool base about the central axis. The central hub comprises a torque input member configured to receive a torque input. The plurality of clamps are slidably coupled to the tool base, and configured to displace bi-directionally along a radial axis. The cam actuator mechanism couples each of the plurality of clamps to the central hub. Rotation of the central hub relative to the tool base causes the cam actuator mechanism to move each of the plurality of clamps in a radial direction.

A tool for engaging drive flanks of a threaded nut has a tool body with a central cavity. Cam surfaces are formed in an inner wall of the central cavity. A retainer secured within the central cavity has an outward-facing slot. A jaw for each of the cam surfaces has a curved outer side in contact with one of the cam surfaces and a drive surface on an inner side for engaging one of the drive flanks of the nut. A foot extends inward from a lower end of each of the jaws into the slot to retain the jaws within the central cavity. Rotating the tool body relative to the jaws moves the drive surfaces of the jaws from a retracted position to a gripping position in engagement with the drive flanks of the nut.
