A fastener-installation system is described that includes a driver to drive a fastener into a structure and a fastener feeder to load the fastener into a loaded position of the driver. The fastener feeder includes a fastener magazine to hold a plurality of fasteners. The fastener-installation system further includes a driver head having a plurality of jaws moveable between a closed position and an expanded position. In the closed position, the plurality of jaws form a piercing tip to pierce material of the structure. Further, the jaws spread apart the material of the structure when the jaws move from the closed position to the expanded position to create a path through the material through which the fastener is driven.

A spring tool for actuating explosive fasteners for driving nails into a substrate is disclosed. For the tool to operate at its maximum potential the firing pin guide should be pushed securely against the rear of the fastener and the tip of the fastener should be pushed securely against the substrate. The action of the operator pushing the tool forward to actuate the tool moves the trigger body forward while compressing the firing spring until the trigger body travels the exact distance needed to release the trigger ball. The trigger body must also be in optimal rotational orientation with the tool and means for accomplishing the alignment is disclosed.

An accessory attachment for a driven fastener hand tool is disclosed comprising a mounting block having an attachment channel and an indexing guide feature. A plate for covering a fastener driving channel of the fastener tool has a nose end with chamfered edges on opposing sides towards the fastener driving channel and the attachment channel has opposing lips for seating against the chamfered edges of the nose end of the plate. One or more bolts through the mounting block at a bottom of the attachment channel press the nose end of the plate causing the opposing lips of the mounting block to press against the chamfered edges thereby securing the mounting block to the nose end of the plate. Alternately or additionally, the mounting block can be used to support a range of accessories including, a non-marring pad, a light, such as an LED, a level, and/or an edge guide.

An apparatus for driving fasteners including a cylinder, a driving piston arranged for driving a fastener from the apparatus into a substrate, the piston being arranged for reciprocating movement relative to the cylinder, a charge supply for feeding a charge to a combustion chamber of the cylinder where the charge is combusted to drive movement of the piston relative to the cylinder, a coil feed of fasteners, and a guidance system configured to guide the apparatus relative to the substrate, the guidance system including a positive placement system.

An apparatus for driving a fastening element in a driving direction into a base material, having a receptacle for the fastening element, from which the fastening element is driven into the base material, having a magazine for supplying fastening elements in a transport direction to the receptacle, wherein the side of the magazine facing the driving direction has a slot which runs in the transport direction, and having a dust deflector which covers the slot.

A striker includes a base portion, a striking portion, and two reinforcing ribs. The base portion has opposite slide surface and base surface, and a front end surface connected between the slide and base surfaces. The striking portion is formed on the front end surface, and has a maximum width in a direction perpendicular to a longitudinal axis smaller than a width of the front end surface. The reinforcing ribs are connected to the base portion. Each reinforcing rib has first and second edges disposed respectively distal from and proximate to the base surface in a direction perpendicular to the longitudinal axis, and disposed respectively distal from and proximate to the striking portion in a direction parallel to the longitudinal axis.

A power tool, comprising first and second module, removable from the first module, the first and second modules being insertable into one another along an insertion axis defining an insertion direction, the first module having a pressing inhibiting element, moved along with the second module, and a pressing blocking element, the inhibiting element being turnable with respect to the blocking element about the insertion axis between normal and detaching positions, the second module being held against the first module in the normal position and removable from the first module in the detaching position, the blocking element allowing the inhibiting element to be transferred along the insertion axis toward the first module into a pressing position when the inhibiting element is in the normal position, the blocking element blocking the insert fitting from being transferred into the pressing position when the inhibiting element is in the detaching position.

A fastener system comprising a tool and fastener is contemplated. The tool comprises an elongated member having a longitudinal bore that receives the fastener. The fastener is driven by the tool into a working surface whereby first and second vents capture a portion of the propellant gas to optimize penetration of the fastener and reduce the sound level. The fastener typically has a first diameter and a second diameter that meet at a step. A washer can receive the first diameter of the fastener. It is contemplated that the alignment of the fastener as it penetrates the work surface is maintained by at least one of (i) the head of the fastener and the longitudinal bore, (ii) washer, and (iii) a clip to reduce failures and spalling.

A replaceable positioning tip can be removably fixedly coupled to a distal end of the trip arm. The positioning tip can define a tip nail guide groove having a proximal portion extending at a first angle substantially parallel to a nail driver axis and a distal end tapering at a second angle. The tapered distal end can be encompassed by a thin-walled portion. A nail tip lifter can be coupled to the rear nail guide housing for pivotable movement between a first position adjacent the positioning tip and a second position away from the positioning tip. The nail tip lifter can define a lifter nail guide groove extending from its inception at a proximal end to a distal end. A biasing member can be positioned between the rear nail guide housing and the nail tip lifter to bias the nail tip lifter toward the first position.

A spad setting tool includes a housing portion including a spad setting assembly receiver and a trigger. A spad setting assembly is operatively coupled to the housing at the spad setting assembly receiver. The spad setting assembly includes a spad receiving member having a spad receiving zone, and a spad retaining element. The spad retaining element is configured and disposed to retain a spad in the spad receiving zone regardless of an orientation of the spad setting assembly.
