An aspect of some embodiments of the current invention relates to a positioner for holding one or more fasteners (e.g. screws and/or nails) which allows a user to push the fasteners out directly into a target material. For example, a user may locate the positioner over a location on the target material and/or drive the fastener through the positioner into the target. In some embodiments, the positioner includes multiple fasteners, for example the positioner maybe used as a magazine of fasteners and/or a storage box for fasteners. Optionally, the positioner includes a hard frame and/or a soft passage holding the fastener. For example, a fastener is inserted into the top of the passage and driven (e.g. pushed, hammered and/or screwed) through, out the bottom of the passage into the target. Optionally, multiple positioners may be arranged along a guide

Discussed is a bolting device that effectively protects an internal configuration of a battery pack and increases manufacturing efficiency during a bolting operation. The bolting device for manufacturing a battery pack includes an electric screwdriver provided with a rotation motor; a driver bit connected to the rotation motor to enable a rotation movement and configured to rotate a bolt; a bit guide member provided with a hollow tube such that the driver bit is inserted into an inside of the hollow tube to be movable; and a guide jig provided with a main body configured to be mounted on an upper portion of a pack housing, the main body having a plate shape and having at least one through hole, and a fixing member inserted into the through hole and mounted therein, and having an insertion hole.

A device for the automatic manufacture of screw connections by a screw includes a motion system with which the screw can be led to the components to be connected. The screw is taken up by an automatic screwing arranged on the motion system. A protective sleeve is arranged so that it can be moved with the automatic screwing unit. The protective sleeve acts as protection, surrounds the screw, and is arranged out of contact with one of the components to be connected.

A fastener device is disclosed. The fastener device includes a hub defining a bore, an attachment shank including a proximal stop and distal bit received within the bore, a retainer releasably engagable with a proximal end of the hub and a defining a passageway for a proximal mounting end of the attachment shank, a biasing element engaged with the proximal stop, and a split cam assembly disposed within a distal end of the bore. The split cam assembly is biased toward a closed configuration for engaging and retaining the head of a fastener, and is piovtable upon distal advancement of the attachment shank and distal bit, against the head, to release the head from engagement with the split cam assembly.

A screw starting device is provided. The screw starting device includes a body, an adjustment assembly and a screw holder. The body includes a screw holding portion and an indexing surface. The adjustment assembly is integral with the screw holding portion. The screw holder is removably attachable to the adjustment assembly. The screw holder includes an insert selected from a group of inserts respectively compatible with screws of varying types. The adjustment assembly is operable to adjust a location of the screw holder relative to the indexing surface.

A wrench for removing and installing a water tank in a plumbing and/or heating system as shown and described herein can include, an elongated handle portion having opposed proximal and distal ends, and a crescent shaped head portion operatively associated with the distal end of the elongated handle portion. The head portion can include an opening that is adapted and configured to match the hexagonal dimensions of two different common threaded connectors.

An installation tool fastener is particularly adapted for fastening a top plate to a roof support member and other structural connections and is particularly adapted for use with an installation tool. The installation tool fastener has a head with a maximum head diameter and a recess for coupling with a drive coupler. The shank of the head has an unthreaded portion and a uniform thread which has a major diameter approximately equal to the maximum diameter of the head. The head preferably has a slight taper. The thread preferably has a 7.5 thread per inch pitch and a thread angle from approximately 25 to 45. In one embodiment for a 6 inch fastener, the thread length is approximately 5 inches and extends along the tapered distal tip.

A fastener guide defines a downward opening funnel having an upper end that transitions to an elongated barrel in which a drive feature is movably disposed. The funnel can fit over an upright fastener so that a head is guided into and enters the barrel a distance so the drive feature can align and register with the head in the barrel before the drive feature advances the fastener through the funnel. The guide can include a guide sleeve and a biasing element interposed between the sleeve and the barrel to urge the barrel from a retracted mode to an extended mode. The barrel can telescope relative to the sleeve in transitioning from the extended mode to the retracted mode, for example, when the funnel engages a board and the drive feature advances the fastener. The biasing element can compress during this telescoping. Related methods of using the guide are provided.

Position indicator tools systems and methods for use with an elongated adapter are disclosed. Tools are configurable to engage the distal end of the elongated adapter include a first member wherein the first member has a distal end and two projection elements positioned in a plane and a channel between the projection elements further wherein at least one of the first members has a notch at a distal end on a channel-facing side, a positioning member formed integrally with the first member wherein the positioning member has a linear marker on a first side, an angled marker on a second side, and a rocker positioned between the angled marker and the channel.

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.
