An adjustable-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 pass-through hand tool includes a handle that includes a hollow bore extending therethrough. The pass-through tool includes a reversible main barrel, having a pair of socket ends and a hollow interior therebetween. The reversible main barrel is insertable into the hollow bore of the handle in either of two orientations to present one of the sockets. The pass-through tool includes a reversible secondary barrel having another pair of sockets and a hollow secondary interior therebetween. The reversible secondary barrel is insertable into the hollow interior of the reversible main barrel in either of two orientations to present one of the associated sockets. The pass-through hand tool includes a reversible tertiary barrel having another pair of sockets and a hollow tertiary interior therebetween. The reversible tertiary barrel is insertable into the hollow interior of the reversible secondary barrel in either of two orientations to present one of the associated sockets.

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 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.

A socket is provided, including a first member, a second member and a third member. The second member is movably inserted within the first member. The third member is movably sleeved with the first member.

Adjustable fastener tools are provided for engaging socket heads. The tool includes a support member, multiple engagement fingers, and an adjustment mechanism. The support member has multiple radially-extending tracks, and a central opening, and the fingers are associated with, and slidable along, the radially-extending tracks. The fingers include at radially inner ends jaws with respective contact surfaces for engaging the socket head. The adjustment mechanism resides, at least in part, within the central opening in the support member, and couples to the fingers. The adjustment mechanism includes an actuating member and multiple hinged trusses. A hinged truss of the trusses is hingedly coupled at one end to the actuating member and hingedly coupled at an other end to a respective finger of the engagement fingers. Movement of the actuating member results, via the hinged truss, in slidable movement of the respective finger along its associated radially-extending track.

According to one aspect, a fluid control system is provided comprising a servicing tool set and at least one valve assembly comprising an actuator and a valve operationally engageable therewith; each valve comprising a valve body; each actuator comprising an actuator body having an upper base and side walls; wherein each actuator body is engageable with a valve body, and wherein the system is configured to allow: engaging the servicing tool set with an actuator and subsequently applying torque to an actuator body engaged with a valve body and thereby disengaging the actuator body from the valve body; the at least one valve assembly comprising at least one Normally Closed (NC) valve; wherein the NC valve is configured to allow activating an actuator engaged therewith with pressurized fluid and thereby opening the NC valve, wherein the actuator comprises a nipple and the servicing tool set comprises a ratchet and at least one socket engageable with the actuator body, and wherein the at least one socket is sized and shaped to accommodate the nipple, and wherein the servicing tool set is further configured to allow operationally coupling the pressurized fluid to the actuator.

Torque adapter for a cable connector that expands to fit connector nuts of different sizes. The adapter fits around the cable connector and engages three of the corners of a hex nut with matching recessed regions in its inner surface. It has three slots that receive the other three corners of the connector nut. The adapter is flexible so that the slots may widen to accommodate connector nuts of larger widths. The outer surface may be hexagonal so that a wrench or similar tool may be used to turn the torque adapter.
