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.

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 ⅜ drive adjustable socket apparatus comprised of a three jaw socket members which ride triangularly and radially within an upper cylindrical tapered housing. The jaw members are abutted inward at 15 degrees to the jaw housing radial walls of the same angular taper. Each jaw member has an inner 120 degrees V-notch which becomes a hexagonal configuration when they are trilaterally spaced apart to accept standard hexagonal configured nuts and bolt type fasteners. The adjustable socket apparatus has a ⅜ inch driver end which has a two slotted windows to allow the use of thumb and index finger to rotate the inner serrated wheel that is exposed through both opposite window slots on the bottom portion of the adjustable socket embodiment. The lower driver end of the adjustable socket has a ⅜ square cavity to accept male universal ratcheting driver. The adjustable socket's driver embodiment also has an internal serrated fixed wheel and a right hand threaded central actuator unit which is solidly affixed onto the vertical shaft. When the serrated wheel is manually rotated, it influences the three jaws to either move upwards or downward depending on the axial rotation of the main vertical thread. The three jaws maneuvering is accomplished by a smaller, upper diameter actuator ring horizontally seated at the lower limb of each jaw member to influence its movement in either an upward or downward and tapered motion. The main vertical thread screw is attached to the vertical adjusting wheel which is secured by the horizontal retention snap ring located beneath an internal groove just above the said serrated wheel. As the user rotates the exposed serrated wheel and its vertical threaded vertical internal screw, it will activate the smaller diameter upper horizontal wheel upwards or downwards as the main vertical thread and serrated gear is being manually rotated on its Z axis. This actuates the threaded adjusting horizontal ring which is housed within the three jaw members' lower slotted or pocket features. The upward and or downward, X coordinate rotation will influence the jaw members to move in either an upward or downward motion at a 15 degree inward angle and ride within the tapered cylindrical walls of the upper jaw housing at the same 15 degree angle. Either a clockwise or counterclockwise rotation causes the main central right hand threaded actuator wheel, when rotated, to move the jaws upward and/or downward because of the influence of the main vertical threaded screw.

A tap holder includes a body extending along an axis and having a front end portion defining a front opening and an externally threaded portion. A gripping assembly includes a spring having first and second legs, a first jaw mounted to the first leg, and a second jaw mounted to the second leg. Each jaw has a tapered outer wall and an inner wall with the inner walls of the jaws facing each other. A sleeve has an internally threaded bore threadably received on the externally threaded portion of the body, and an inner tapered surface configured to abut the tapered outer walls of the first and second jaws. As the sleeve is rotated relative to the body, a distance between the first and second gripping surfaces may be adjusted for gripping a tap between the inner walls of the first and second jaws. Each of the inner walls includes first and second gripping surfaces, the first gripping surfaces defining a first width therebetween for gripping taps having a first range of head sizes, and the second gripping surfaces defining a larger second width therebetween for gripping taps having a second, different range of head sizes.

A tool has a body with an axially extending cavity containing partly cylindrical receptacles. Each receptacle has an opening facing inward toward the axis. A partly cylindrical cam portion of a jaw fits within each of the receptacles. Each jaw has a workpiece engaging portion protruding from the body. Each of the cam portions has a pair of flat flanks that protrude inward from the opening of one of the receptacles. The flat flanks intersect each other at an inner corner. Each flank abuts one of the flanks of another of the cam members. Each of the engaging portions has an outer surface configured to engage a hole within the workpiece. An increment of rotation of the body relative to the jaws causes the inner corners of the flanks to move outward from the axis and the outer surfaces of the engaging portions to move from a contracted position to an expanded position.

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.
