An apparatus providing a platform for installing screws can include a cart with wheels, an assembly rail system mounted to the cart, and a screw assembly mounted to the assembly rail system. The screw assembly can include a screw feeding device, a screw guide tube, and a screwing device such as a drill that rotates a drive shaft that engages a screw received from the screw guide tube. The screw feeding device can include a screw rack that holds screws, and a magnetic grip that moves a screw from the screw rack to a screw feeding tube that is connected to the screw guide tube. The screw guide tube can include bristles for centering a screw received from the screw feeding tube. The apparatus can include a computer control system that operates the screwing device and the screw feeding device.

Elongated fastener driving apparatuses are disclosed. The drivers are operable to quickly and accurately install fasteners from a standing position on, for example, a floor surface.

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 magnetic driver bit holder may include, but is not limited to: a drive portion including: a shaft portion including: a recess disposed in an end portion of the shaft portion; and one or more magnets disposed within the shaft portion, and a sleeve portion including: a hollow tube dimensioned such that the shaft portion may be inserted into the hollow tube; and a ring magnet coupled to an end portion of the hollow tube.

A screwdriver includes a first section, a second section where a positioning groove is annularly formed, a sleeve member detachably disposed on the second section, and an engagement member disposed in the sleeve member. The sleeve member has a body with a through hole, a magnetic unit disposed in the through hole, and an accommodation groove adapted to accommodate the engagement member. When the second section and the sleeve member engage in position, the accommodation groove and the positioning groove meet to engage the engagement member with the positioning groove. The engagement between the second section and the sleeve member allows a gap to be formed between a screw head and the sleeve member while inserting the second section into a socket of the screw head, so the magnetic attraction exists without the contact between the sleeve member and the screw head for a firm engagement therebetween.

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 fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.

An installation tool and related methods are provided. The tool can pull a strip of collated fasteners along a collated fastener path to a guide, where individual fasteners are sequentially separated from the strip and advanced into a workpiece. The tool can include a tension feeder located downstream of the guide. The tension feeder is configured to apply tension to the strip between the guide and a leading end of the strip. The tool can include a driveshaft configured to attach to a conventional drive tool chuck or a drive tool having hexagonal type drive components. The guide can be one piece and replaceable, with a guide body and a guide head. A strip slot can be defined in the same to align a fastener head with a backstop and facilitate entry of a fastener shank in a feed slot. Related methods of use are provided.

An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive threaded fasteners at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide head assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating or reference structures function to properly precisely set the drive angle of the fastener. Various indicators mounted to the guide head indicate the flush position of a locating surface or reference structure. The flush indicators may employ a projection, a flag, an LED or an audio module.

The invention relates to a robot for tightening bolt nuts on a vehicle chassis, the robot comprising a polyarticulated arm at the end of which is a nut tightening tool. A sleeve-shaped centering member is fixed around the nut tightening tool and comprises a frustoconical surface which makes it possible, on contact with a nut, to reposition the nut tightening tool automatically in the axis of the nut.
