摘要： A screw including a shank, at least one screw thread, which is arranged on the shank, winds around the shank and protrudes from the shank, and a separate helix element, which is arranged non-monolithically on the shank, wherein the separate helix element winds around the shank, protrudes from the shank, and constitutes at least a section of the at least one screw thread. The screw further includes at least one first claw, which projects from the shank, and which has both radial and axial overlap with the separate helix element, wherein the shank and the at least one first claw are monolithic with respect to one another.

摘要： Various embodiments of a fastener driveable into a substrate are provided. The fastener includes a head, a shank, and a helical thread formation. Portions of the shank and helical thread formations may be tapered. The outer diameter of the shank may decrease in a direction away from the head. An outer diameter of the thread formation may increase in a direction away from the head. The head may include a plurality of extending ribs. The helical thread formation may be formed with a plurality of grooves that are respectively each partially defined by a straight cutting edge. These improvements reduce torsional failure of the fastener from over tightening.

摘要： A cement board screw a high thread that begins on the tapered end, extends onto the shank and terminates at a second axial location along the shank. The high thread defines a high peripheral edge, where a leading flank and a trailing flank meet at the high peripheral edge and together define a high thread angle that is between about thirty degrees and about fifty-five degrees. A low thread begins on the tapered end, extends onto the shank and terminates substantially at a first axial location along the shank such that an axial length of the low thread is less than an axial length of the high thread. The low thread includes a leading flank and a trailing flank that meet at a low peripheral edge and together define a low thread angle that is between about fifty degrees and about seventy degrees.

摘要： The invention relates to a system for joining two components or for reinforcing a component, comprising a first and a second threaded sleeve which each comprise the following: an outer thread, with the aid of which the threaded sleeve can be screwed into the respective component and which is suitable to form a composite with the respective component, and a power drive, by which a torque for screwing the threaded sleeve into the respective component can be transmitted to the threaded sleeve. The system further comprises an elongate clamping element which is suitable to be guided through the second threaded sleeve and introduced into or guided through the first threaded sleeve, and which is suitable to axially clamp the first and the second threaded sleeve in such a manner that the first and the second threaded sleeve form opposed composite stresses in the respective component.

摘要： A method produces a composite component from a first joining element and a second joining element by use of an adhesive and a flow drill screw. Before attaching the second joining element to the first joining element, a recess is made around the at least one screw position in which the respective flow drill screw penetrates the second joining element, in a joining surface of the second joining element.

摘要： A wood screw includes a head, a shank axially extending from the head, a main thread extending helically around the shank in a tightening direction and having an outer diameter ranging from 3 to 16 mm, and a plurality of forward ribs extending spirally around the shank in a same direction as the main thread. The number of the forward ribs ranges from three to five. Each forward rib, in a cross section thereof, has a first outer edge facing the tightening direction, and a second outer edge facing opposite the tightening direction and having a length shorter than that of the first outer edge. Each forward rib has a height smaller than that of the main thread, and a lead angle greater than that of the main thread.

摘要： A structural screw usable in multiple different substrates/materials includes a head end, a shank and a tapered end, the head end including a tool engaging part, the head end located at a first end of the shank and the tapered end located at a second end of the shank. A thread is formed along the shank, wherein the thread begins on the tapered end, extends onto the shank and terminates at a first axial location along the shank that is spaced from the head end. The thread (i) is a multiple start thread formed by at least a first helical thread and a second helical thread and/or (ii) includes a thread angle of between fifteen degrees and thirty degrees. The screw may also include a reaming section with leading and trailing wedge sections and/or an asymmetric notch pattern along at least part of the thread edge.

摘要： A self-drilling screw structure comprises a screw head and a screw rod extending outwardly from the screw head. The screw rod is formed with a drill bit section at one end opposite to the screw head, a drill tail section and a screw thread section. The drill bit section comprises two first cutting edges extending helically and intersecting at a chisel edge. Two first chip flutes located at the positions respectively between the two first cutting edges and extending from the chisel edge toward the drill tail section. The drill tail section comprises two second cutting edges extending helically toward the screw thread section. Two second chip flutes located at the positions respectively between the two second cutting edges and extending helically toward the screw thread section. Each first chip flute and the second chip flute form a connection at joint between the drill bit and drill tail sections.

摘要： A self-drilling, anti-burr, threaded fastener is provided having at least two different thread portions. The first thread portion extends along the tip and the second thread portion extends along the tapered portion adjacent to the tip. A third thread portion can be provided between the first and second thread portions that includes a plurality of axial gaps that extend to the thread root to remove burrs. Alternatively, knurling is provided in an area where the first and second thread portions meet, and the knurling acts to remove burrs.
