Provided is a wiring unit in which it is possible to limit the height dimension. The wiring unit is provided with a plurality of electrical wires, a plate on which a support surface for supporting each of the electrical wires is formed, and a holding member. The holding member has a flat pressing surface arranged to be approximately parallel with the support surface of the plate. The electrical wires are arranged in a row and held between the pressing surface and the support surface.

An impact device includes a drive assembly, a cam having a ramp and a fall-off, and a follower associated with the cam. During rotation of the cam, one of the cam or the follower axially displaces as the follower traverses the cam and falls off the fall-off to transform the rotary motion of the drive assembly to a reciprocating motion having a saw-tooth shape that includes a gradual retraction and a quick extension. The quick extension creates an impact loading, which can be used, for example, for driving a fastener into a work piece.

A staple is provided with two legs each including a forward projection; and a connection member having two ends formed with tops of the legs respectively. In another embodiment, each leg further has a rearward projection. In still another embodiment, the staple is shaped as an L. In yet another embodiment, the staple is shaped as a T.

A staple includes a crown section having diamond shaped with a first curve, a second curve, and a third curve representing three points of a diamond. The crown section having opposite ends. A pair of leg sections extend from the opposite ends of the crown section.

A polymeric fastener for use in the construction industry for fastening wood and other basic materials together. The polymeric fastener can be formed in the basic shape of a nail and/or a staple-like fastener. Preferred embodiments of the polymeric fastener include a hardened binder embedded with a filler and/or a core for adequate strength as required for use with a delivery device powered by pneumatics, hydraulics, or other mechanical systems.

A powered fastening device is provided and is capable of applying multiple strikes to a fastener to drive the fastener to a preselected depth in a work piece and then automatically stopping the strikes when the preselected depth has been achieved.

A staple-refill 11 is provided with: a casing 12 in which a plurality of sheet-type connected staples 10 are stacked; a staple inserting port 14; a staple discharge port 16; a cover member 15 which covers the sheet-type connected staples 10 in the casing 12 from a side of the staple inserting port 14; and a notch portion 18 formed in the casing 12 and extending from an edge of the staple inserting port 14 in an insertion direction.

A clamp arrangement for tree trunks with a main body on which at least three retaining tongues are formed, arranged at a distance from one another, wherein the main body and the retaining tongues are oriented, as blades, in a common cutting direction, and wherein at least two snap lugs are formed on the main body and/or on at least one retaining tongue to allow a detachable connection with a setting tool.

A fastener cap assembly for securing protective wrap to lumber includes a plurality of fastener caps spaced from one another by breakable tabs along a first axis extending through a center of the fastener caps, with each of the fastener caps and breakable tabs comprising a substrate formed from a paper-based material. The fastener cap assembly further includes a groove extending across a center portion of the breakable tabs and penetrating inward from the top surface of the breakable tabs to a predetermined depth, and a protective material applied to at least the top surfaces of the substrates that forms a non-waxy and moisture-resistant protective harrier when cured.

A substrate mounting clip includes a plate having a first side and a second side. A first arm extends from the first side of the plate. The first arm includes a first projection shaped and dimensioned to secure the plate to a first substrate. A second arm extends from the second side of the plate. The second arm includes a second projection shaped and dimensioned to secure the plate to a second substrate proximate to the first substrate. An aperture is formed in the plate between the first arm and the second arm.
