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.

Single motion magazine retention for fastening tools

A fastening tool of the present invention includes a housing having an underside. The fastening tool also includes a magazine and a support foot connected to one of the housing underside and the magazine. Using a system of cooperating detents formed on the support foot and housing underside (or magazine, as the case may be), the support foot can be quickly and easily removably secured to the fastening tool without using any tools.

A barbed staple for installing fencing wire onto a fence post. The staple has a crown section and a leg section. The crown section has an arcuate crown portion and a radiused portion, and the leg section has a pair of leg portions that extend in parallel from the radiused portion of the crown section. At least one barb protrudes from each of the leg portions, the barb having projecting points. The distance between the distal edge of the projecting points defines an outer leg width. The crown portion of the crown section has a greater width than the pair of leg portions in parallel. The outer crown width is greater than the outer leg width.

A stapling tool assembly may include a nosepiece assembly with a driver channel through which a staple is driven into a workpiece. The stapling tool assembly may also include a wire alignment contact trip with a contact foot. The contact foot may include a peripheral guide wall that defines a workpiece contact edge. The workpiece contact edge may include at least one wire alignment recess and at least one opposing wire alignment recess in the workpiece contact edge. The at least one wire alignment recess and the at least one opposing wire alignment recess can cooperate to define a first and a second wire positioning path to align the wire in two different orientations relative to the drive channel. The at least one wire alignment recess can have a first overall length that is different than a second overall length of the at least one opposing wire alignment recess.

An electric fastener driving tool assembly can include a driver designed to drive a fastener into a workpiece. The driver can reciprocate along an axial driver path between an extended position and a home position. A home position sensor can be located laterally adjacent the axial driver path. The home position sensor can be located to sense the presence of the driver in the home position when a lateral distance between the driver and the sensor changes.

A driver return assembly can be positioned to return a concrete nail driver of a cordless electric powered nailer to the home position. A return rack can be fixedly coupled to and positioned along a longitudinal length of the concrete nail driver The driver return assembly can include a solenoid driving a plunger in a reciprocating motion in a homeward direction and a driven direction. A return pawl can be coupled to the plunger and pivotable into a pawl raised position relative to the plunger in which the pawl is engageable with the return rack during movement of the plunger in the homeward direction, and pivotable into a pawl lowered position relative to the plunger in which the pawl is not engageable with the return rack during movement of the plunger in the driven direction.

Return mechanism for a cordless nailer

A flange nut for use in mounting a power tool component onto a rotatable spindle of a power tool. The flange nut includes one or more non-circular apertures into which an end of a shaped tool such as an Allen wrench may be inserted. Torquing or otherwise applying a force to a portion of the shaped tool serves to thread the nut along the spindle either towards the power tool component to secure the power tool component on the spindle or away from the power tool component to allow for removal of the power tool component.
