A method of installing a plurality of nut and bolt fasteners upon a structure is disclosed. The method includes placing a jig around the nut of a first fastener and the nut of a second fastener, securing the jig to the first fastener, and then using a power tool to tighten the nut of the second fastener to a target torque. The step of tightening the nut comprises engaging a socket portion of the power tool with the nut, securing the power tool to the jig such that a handle portion of the power tool is prevented from rotating about an axis of rotation of a socket portion of the power tool when the nut is being rotated by the socket portion. A jig, jig fasteners for securing a jig to a fastener, and a fastening head for a power tool are disclosed.

Surgical impact driver adaptors may be connected between a powered surgical instrument and a driven surgical device when performing surgical procedures, such as those involving the implantation of a surgical implant into bone, for example. During surgical procedures, the surgical impact driver adaptors may limit a transfer of a rotational force from the powered surgical instrument to the surgical device until a sufficient axial force is applied to the impact driver adaptor from the powered surgical instrument.

An attachment part for a power tool includes an elongated housing including an upper housing part, a lower housing part and an interconnection structure that interconnects the upper and lower housing parts. An input gear for connection to an output shaft of a power tool is arranged at a first end of the housing. An output gear with an output interface is arranged at a second end of the housing. The interconnecting structure includes a sleeve member extending through a first central bore at the first end of the upper housing part, which sleeve member receives the input gear, and a fixation member extending through a second central bore at the first end of the lower housing part and which is arranged to be secured to the sleeve member to clamp the upper and lower housing parts. A tool assembly includes a power tool and the attachment part.

A lockable adapter is configured to couple a drive socket to a tool. The lockable adapter includes a body defining a longitudinal axis. The body is configured to couple the lockable adapter to the tool. The lockable adapter includes a sleeve moveably coupled relative to the body along the longitudinal axis of the body between a first position and a second position. The sleeve is configured to interface with the drive socket to support the drive socket on the sleeve. The lockable adapter includes a collar moveable relative to the sleeve. The sleeve moves into the second position configured to lock the drive socket to the sleeve in response to inserting the drive socket onto the sleeve. The sleeve moves into the first position configured to allow removal of the drive socket from the sleeve in response to moving the collar relative to the sleeve.

Embodiments relate to a power drive adapter tool. The tool includes a drive adapter and a drill bit assembly. The drive adapter includes a body having a first end and a second end, the first end having a drive-receiving aperture configured to receive a drive from a drive tool, and the second end having a bit-receiving aperture configured to receive the drill bit assembly. The drill bit assembly has a drill bit and a connector, the connector having a proximal end and a distal end. The drill bit is permanently connected to the distal end, and the proximal end is configured to insert into the bit-receiving aperture.

A tool extension adapted to couple to a drive lug of a driver and a tool that allows the tool to reach hard to reach places without room for a coupling. The tool extension voids the need for a larger diameter coupling by including a female recess in an end of the tool extension that receives the bit into the shaft itself.

Methods for using installation tools are disclosed. Fastener installation tools engage the distal end of an elongated. Two projection elements positioned in a plane on the installation tool and a channel between the projection elements further are positionable to provide a marker for a user during use to achieve an optimal installation location.

A motor starting assembly for starting a pull start motor includes a cup that is attachable to a flywheel of a pull start motor. A cylinder is insertable into the cup and the cylinder engages the cup when the cylinder is rotated in a first direction. In this way the cylinder can rotate the crankshaft of the pull start motor for starting the pull start motor. The cylinder disengages the cup when the when the rotational speed of the cup exceeds the rotational speed of the cylinder. In this way the cylinder facilitate the pull start motor to run without rotating the cylinder. An adapter is releasably attachable to the cylinder and a power drill thereby facilitating the power drill to rotate the cylinder when the power drill is turned on for starting the pull start motor.

Motor-driven portable tool configured so as to ensure the expansion of a wall anchor (Ch) of a screw (Vs) and wall anchor (Ch) set, with fine setting of the determined stroke of the effector.

Disclosed is a drill attachment device comprising a transfer gear configured to rotate about an axis perpendicular to the axis of a drill used to power the transfer gear. The transfer gear may comprise an open-ended slot which provides a passageway through which a threaded rod may pass. The open-ended slot may further be configured to retain a mechanical nut, enabling a user to run a threaded rod through the open-ended slot for driving the nut along the rod. The transfer gear may also support an external driver, and the drill attachment device may comprise guide slots configured to position the rod and/or nut against the external driver for driving a nut up or down rod.
