A powered fastener driver includes a magazine in which fasteners of a first length or fasteners of a second length greater than the first length are receivable. The magazine includes a shear block, a loading portion, and a feed channel extending lengthwise through the magazine between the shear block and the loading portion. The loading portion includes a first slot and a second slot that are each configured to receive fasteners of the corresponding first and second lengths for entry into the feed channel. The loading portion also includes a pivot member configured to prevent fasteners of the first length from being loaded into the second slot corresponding to the fasteners of the second length. The pivot member is pivotable about a pivot axis between a first, blocking position blocking access to the second slot, and a second, bypass position permitting access to the second slot.

A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

A powered fastener driver includes a magazine in which fasteners of a first length or fasteners of a second length greater than the first length are receivable. The magazine includes a shear block located at a first end of the magazine, a loading portion located at a second end of the magazine, and a feed channel extending lengthwise through the magazine between. The loading portion of the magazine includes first and second slots configured to receive fasteners of the corresponding first and second lengths for entry into the feed channel, and a feed channel access gate configured to prevent fasteners of the first length from being loaded into the second slot. The feed channel access gate is configured as a pivot member pivotable about an axis between a first, blocking position, and a second, bypass position. A spring biases the feed channel access gate toward the blocking position.

Various embodiments of the present disclosure provide a battery-powered stapling tool.

A driving tool includes an electric motor, a battery mount that receives a battery for powering the electric motor, a flywheel that rotates by the electric motor, a magazine that loads a connected fastener rolled in a coil and including a plurality of fasteners temporarily connected in parallel, an impact driver that advances through a driving path with rotational power of the flywheel to drive the fasteners, and a feed mechanism that feeds the connected fastener by a pitch from the magazine toward the driving path.

A fastener driver includes an outer cylinder having a first end and an opposite, second end, an inner cylinder positioned within the outer cylinder, a moveable piston positioned within the inner cylinder, a driver blade attached to the piston and movable therewith between a top-dead-center position near the second end and a bottom-dead-center position near the first end along a drive axis and a frame that extends from the first end. The frame is integrally formed with the outer cylinder as a single piece

A fastener driver includes a housing defining a head portion and a handle portion, a drive mechanism positioned within the housing, and a firing mechanism. The firing mechanism includes a primary guide member supported within the head portion of the housing, a secondary guide member spaced from the primary guide member and supported within the head portion of the housing, a piston slidable along the primary guide member and the secondary guide member, a driver blade attached to the piston and configured to be movable along a drive axis, and a biasing member configured to move the piston and the driver blade from a top dead center (TDC) position toward a bottom dead center (BDC) position. A lifter assembly is operated by the drive mechanism to return the piston and the driver blade towards the TDC position, against the bias of the biasing member.

A fastening tool having a dry fire lockout assembly connected to and operatively engaged with a magazine assembly that prevents the tool from driving a fastener with there is less than a predetermined number of fasteners in the magazine assembly and an indicator that notifies the user that there is less than a predetermined number of fasteners in the magazine assembly.

A magazine for use with a fastening tool. The magazine can have a pusher assembly that can be retracted into a recess in the magazine to facilitate loading and reloading of fasteners. The pusher assembly can have a pusher assembly knob which can be reversibly latched to a detent to maintain the pusher assembly in a retracted state. The fastening tool can use a magazine which can be reloaded by a method which has a step of reversibly retracting the pusher assembly into the retracted state to allow for feeding one or more fasteners to the magazine.

A fastening tool including a magazine securely and releasably retained on the fastening tool by a cam mounted on one of the fastening tool and the magazine. In a single rotary motion, the cam wedges together the housing member of the fastening tool and the housing member of the magazine, while simultaneously rotating cam lobes into respective chambers formed on the fastening tool and the magazine. The cam rotation and magazine retention system is accomplished without tools.
