An improved fastener for securing a first building component to a second building component is provided. The fastener includes a head, a shank, and a tip. The shank is connected to the head and extends along a longitudinal axis to the tip. The shank includes an upper shank portion, a lower shank portion, and a transition zone. The upper shank portion is located adjacent to the head. The lower shank portion is spaced from the upper shank portion and is located adjacent to the tip. The transition zone is positioned longitudinally between the upper shank portion and the lower shank portion. The transition zone is longitudinally spaced from the head by a pre-determined distance. The pre-determined distance is associated with a thickness of the first building component such that the transition zone is aligned with a joint between the first and second building components.

A screw having a cylindrical shank with a conical tip at one end and a screw head at the other, and at least one thread section therebetween. The thread section has a thread core. On the thread section, multiple successive thread terms are formed on a shell surface of the thread core. In the region of the thread section, multiple elevations are arranged on the outside of the shell surface of the thread core.

A spacing fastener comprises a head and a shaft adjoining the head and ending with a tip. The shaft comprises an anchoring screw thread, an under-head screw thread closest to and ending near the head, and a non-threaded shaft portion therebetween. A support element at a distance circumferentially from the screw-thread end of under-head screw thread forms contact point (Au) therewith. In the region overlapping with under-head screw thread in top view, the support element is spaced apart therefrom and forms a contact point (As) for an outer shell lying between the head and under-head screw thread. The distance of contact point (As) from the head is greater than or equal to difference between the distance of contact point (Au) from the head and a tolerance distance of at most 15% of the major diameter of the under-head screw thread. The support element extends lengthwise over less than 150?.

A screw having a cylindrical shank with a conical tip at one end and a screw head at the other, and at least one thread section therebetween. The thread section has a thread core. On the thread section, multiple successive thread terms are formed on a shell surface of the thread core. In the region of the thread section, multiple elevations are arranged on the outside of the shell surface of the thread core.

A threaded fastener is provided. The threaded fastener includes a shank having a non-threaded portion and a threaded portion. A tip extends from the threaded portion and a head extends from the non-threaded portion. A plurality of wings extend from the shank and are configured to form a passage as the threaded fastener advances. An enlarged portion is configured to seat in the passage formed by the plurality of wings with the threaded fastener in an installed arrangement.

A construction nailing screw is configured to be used in like manner as traditional nails but rotate during driving through threading, providing retention of the construction nailing screw in the construction material(s), and the ability to be removed from the construction material(s) by reverse rotation. The construction nailing screw is characterized by a shank with a head on one longitudinal end, and a tip on another longitudinal end, with external threading that provides minimal friction during installation and mild resistance during removal, and two cutouts extending along the exterior of the shank and through the external threading. The head allows both a manual installation tool and an automatic installation tool to strike the head and drive (install) the nailing screw. The external threading has an upper side with a high pitch relative to the longitudinal axis of the shank, and a lower side with a low pitch relative to the longitudinal axis of the shank.

A low energy wood screw that may be inserted quickly and using less energy than conventional screws. In various embodiments, the screw may include a countersunk head having a recess for accommodating a driving tool, a tapered neck, a plurality of crown ribs extending over the head and neck, a lubricating coating, main threads with a large thread lead, and lower threads having an asymmetrical profile and extending onto a gimlet point.

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.

A flooring screw comprises a screw head, a screw shank connected with the screw head, and a cone connected with screw shank. The screw shank includes a first shank section connected with the screw head, a second shank section connected with the cone, a first thread formed on the first shank section, a second thread extended from the cone to the second shank section and running helically along a direction opposite the direction of the first thread, and a third shank section between the first shank section and the second shank section. The third shank section includes a plurality of peaks protruding outward radially and a plurality of troughs formed between the peaks and recessed radially with respect to the peaks. The peaks and the troughs form an unsmooth surface on the third shank section.

A screw has a shaft section which extends axially, a screw thread at the shaft section, which screw thread has thread turns that extend radially starting from the shaft section, a screw tip section which connects to the shaft section, at least one first scraping edge at the screw tip section, and at least one second scraping edge in a region of the shaft section adjacent to the screw tip section. The at least one first scraping edge and the at least one second scraping edge are spaced at a distance from each other and extend in an axial direction over different areas of the screw.
