A screw holding and dispensing device includes a casing, a number of elastic members latched on an inner sidewall of the casing, and a pressing member received by the elastic member. Each elastic member carries a screw, to release a screw, an external force is applied on the pressing member, the pressing member is driven to move out of the top elastic member, the pressing member moves down and drives out the lowermost screw from the bottom elastic member, and the screw slides into a corresponding screw hole.

A fastener cartridge can be used with a shaft of a tool during an orthopedic procedure. The fastener cartridge can have a main housing that can be attached to fastener housing including a fastener chamber and a backstop component. The fastener chamber includes a plurality of non-flexible tabs and the backstop component includes a plurality of resiliently flexible tabs. The fastener housing is configured to include a plurality of fasteners that are arranged therein such that the longitudinal axes of the fastener chamber and the plurality of fasteners are collinear. The plurality non-flexible tabs prevent one of the fasteners from inadvertently passing entirely out of an outlet of the fastener chamber and the plurality of resiliently flexible tabs allow the fasteners to move axially in the first direction and restrict movement of the fasteners in a second direction opposite the first direction.

A screw driving machine includes a driving piston to which a driver bit is attachable, a driving cylinder partitioned into a first chamber and a second chamber by the driving piston and moving the driver bit when compressed air is supplied to the second chamber, an air motor rotating the driver bit by the compressed air, an air flow path communicating the second chamber and the air motor, a main chamber storing the compressed air and communicating with the air flow path, and a main valve opening and closing communication between the air flow path and the main chamber. The driving cylinder has a supply port communicating the air flow path and the second chamber. A throttle portion is disposed to be displaceable on an outer periphery of the driving cylinder to change an opening area of the supply port.

A screw driving machine includes a contact portion movable from a first position to a second position via a third position by abutting against a driven member to press against the driven member, a driving portion moving a driver bit when the contact portion reaches the third position to drive a screw into the driven member, a tightening portion causing the driver bit to rotate about an axis and tighten the screw after the screw is driven, a tightening depth switching portion switching a tightening depth of the screw by the tightening portion after the screw is driven, a driving depth regulating portion regulating a movement amount of the contact portion between the second position and the third position, and a driving depth switching portion switching whether to regulate the movement amount of the contact portion by the driving depth regulating portion.

The present disclosure is directed to a single-sided deck clip that allows an approach to deck board installation with hidden fasteners, and without grooving both edges of a deck board. By not grooving edges, perimeter trim can include one square finished edge on ending pieces. The single-sided clip allows for attaching fasteners through the clip at an angle that penetrates both a deck board and an underlying joist, thus providing a positive connection of decking to joist framing below. In another embodiment, a clip magazine is disclosed that stores, supplies, and assists in installation of single-sided deck clips and fasteners. The clip magazine can hold a plurality fasteners and single-sided deck clips. The magazine allows the single-sided clips and fasteners to be positioned relative to the deck board, and allows fasteners to be aligned with a single-sided clip, and pushed into a deck board during installation.

A robot screw-fastening device includes a nut runner that is attached to a distal end of an arm of a robot to fasten screws one by one. A screw magazine accommodates a plurality of screws to be fed to the nut runner. A magazine inserting-extracting mechanism inserts and extracts a screw retrieving position of the screw magazine to and from below the nut runner. The screw magazine includes a flat support surface with a slit-like opening that contacts with a bearing surface of each of the screws so as to support the screws in a hanging state. The slit-like opening allows an underhead section of each screw to extend therethrough so that the plurality of screws are arranged parallel to each other in a single row.
