In various embodiments, a torque controlled driver may include a gearbox, a driver with a torque controller and a motor with a rotating shank, a motor gear coupled concentrically with the rotating shank, a bit drive gear in rotational engagement with the motor gear to drive a bit sized to drive a fastener to secure a thermal transfer device to an integrated circuit package, where the gearbox is to hold the motor gear in a position about a motor gear rotational axis and the drive gear about a drive gear rotational axis such that the motor gear and the bit drive gear maintain rotational engagement as the motor gear rotates. Other embodiments may be described and/or claimed.

A fastening device includes: a support portion including a first end portion, and a second end portion, and a central portion between the first and second end portions; a first pulley, a second pulley, and a third pulley rotatably disposed on the central portion, the first end portion, and the second end portion, respectively; a first connection portion and a second connection portion respectively rotatably disposed on the first and second end portions and respectively connected to the second and third pulleys; a first fastening tool and a second fastening tool respectively connected to the first and second connection portions; and a motor connected to the first pulley, wherein a force generated by the motor and provided to the first pulley is at least partially transmitted to the second and third pulleys to vary a distance between the first and second fastening tools.

A reconfigurable fastener multi-spindle tool system includes multiple spindle assemblies, each including a support ring and a support arm sleeve received in the support ring and rotatable on a central longitudinal axis of the support ring. At least one support arm is connected to the support ring. The at least one support arm rotates with respect to the central longitudinal axis. A spindle is fixed to the support arm and is displaceable with respect to the central longitudinal axis. The spindle has an adaptor to temporarily retain and torque a fastener. A reaction plate is connected to the spindle and has a geometric shape. At least one template plate has multiple openings each having a geometric shape matching the geometric shape of the reaction plate. One of the openings receives the reaction plate thereby preventing axial rotation of the spindle.

A temporary fastening tool has a tool main body, a grip, a transmission mechanism, a socket, a plurality of pins, and two magnets. At least a portion of a side surface of the pin protrudes from an inner surface section of the socket toward a central axis of the socket. The magnets are disposed such that centers of the magnets are disposed outside of an imaginary circle having a radius of a circle that circumscribes an outer circumferential section of a screwing member that includes corner sections. The magnets are disposed at positions that do not overlap the pins when the socket is seen from a side of an opening section.

An improved multi-bolt and nut torque wrench for installing and removing bolts or nuts from flanged joints or the like which includes a plurality of torque stations having a plurality of high torque wrenches for engaging the heads of the bolts or nuts during a high torque phase of removal or installation; a plurality of low-torque motors operatively engaged with the wrenches for rotating the bolts or nuts during the low torque phase of removal or installation; a source of hydraulic fluid for driving the low-torque motors during the low-torque phase, and driving the high-torque wrenches during the high torque phase; and a mechanism for switching between the two phases depending on the torque needed.

Method and apparatus for assembling, with fasteners, components of a structure having an outboard side, an inboard side, and a supporting frame. The components are placed together on the frame. An electromagnet having a core with multiple openings is positioned on the outboard side. A magnetically attractive member is placed against the inboard side opposite and aligned with the electromagnet. When activated, the electromagnet is attracted towards the magnetically attractive member and the two hold the components together. Multiple drill members pass through the openings in the core of the electromagnet and multiple openings are drilled simultaneously through the components. Subsequently, multiple rivets or huck bolts are simultaneously inserted into the drilled openings.
