20080260495 | THREADED SCREW FASTENER WITH MULTIPLE CHARACTERISTIC THREADS - A fastener with multiple thread characteristics includes a shank and head. The shank has a penetrating tip distal most from the head. The shank includes a first, conventional thread formation formed therein adjacent the penetrating tip and a second, anti-back-out thread formation adjacent the conventional thread formation, between the conventional thread formation and the head. | 10-23-2008 |
20080295651 | BRICK TIE ANCHOR AND DRIVE TOOL - A brick tie anchor secures a brick veneer to an underlying structure. The anchor includes a head portion having a shaped body defining a longitudinal axis. The head includes a key portion extending from an end of the body having generally flat sides and an open central area. A shank has an upper shank portion and a lower shank portion. The lower shank portion is threaded for penetration into the underlying structure. The upper shank portion and the lower shank portion are separated from one another by a shoulder. The upper shank portion includes a knurled region extending from the shoulder. A washer is disposed at the juncture of the head portion and the shank. The washer has a diameter greater than a largest measurement across the head portion. The washer includes a resilient sealing element on the side of the washer adjacent to the shank. A driving tool for the anchor is also disclosed. | 12-04-2008 |
20090136319 | THREADED SCREW FASTENER - A threaded screw fastener has a point, a shank and a head. The point is a ballistic point. The shank comprises a linear travel area, preferably unthreaded, adjacent to the point and a threaded area between the linear travel area and the head. The head is a bugle head formed with a Phillips-style recess configured to receive a driver or driving bit. The fastener is configured fasten a surface material to a substrate material and to be linearly driven into the materials before rotation of the fastener is required, thus reducing the number of rotations required to drive the fastener. The fastener is particularly suited to be used with powered driving tools that utilize both linear and rotating driving means. | 05-28-2009 |
20090165600 | PNEUMATIC FASTENER DRIVING TOOL - A pneumatic fastener driving tool is configured to drive a threaded fastener using both linear and rotational motion. The tool allows a fastener to first be driven linearly, without rotation, through a surface material and into a substrate material, preferably to a depth that causes the fastener to at least pierce the substrate material. The tool then rotates the threaded fastener and causes it to fully engage the substrate material, thereby fastening the surface material to the substrate material. The tool has sufficient linear force to drive a fastener into relatively hard substrate materials, such as steel studs, and has a stationary air motor assembly to reduce recoil generated during the driving process. The tool further comprises a gear reducer assembly that uses a compound planetary gear in order to reduce the overall length of the tool. | 07-02-2009 |
20090185880 | Universal fastener - A new and improved fastener wherein the tip portion includes a unique and novel structure that enables and facilitates the insertion of the fastener into both wood and concrete substrates. The tip portion includes a half-cone structure in which a pointed tip is defined between a radially outer conical surface portion and a radially inner flat or planar surface portion. | 07-23-2009 |
20100172718 | Fastener with Shaving Inhibitor - A fastener with shaving inhibitor for fastening a material such as a metal sheeting panel to a substrate such as metal or wood. The fastener has a notch angled leftwardly with respect to an axis of the fastener, the notch having a first end and a second end, a leading face and a trailing face, each face having outer edges and a common edge at their intersection. At least one of the leading and trailing faces may be substantially planar but may have other shapes, such as concave. Leftwardly angled notch with faces having outer edges may attract and then cut shavings formed from material being installed, thereby reducing the quantity and/or length of shavings, prolonging the life of the material or the structure to which the material is fastened. | 07-08-2010 |
20100219317 | Anchor assembly with large range of motion suspension members, and restraint systems for suspended components - An anchor assembly structured for use in connection with ceiling or roofing structures for hanging industrial or commercial components, such as, for example, electrical conduits, heating units, water pipes for automatic water sprinkler systems, and the like. The anchor assembly is easy and quick to install, and also provides enhanced swivel capabilities or angular ranges of movement so as to accommodate various system and spatial requirements in connection with the suspension of the components. Suspension and lateral restraint systems are also disclosed. | 09-02-2010 |
20110002753 | THREADED CONCRETE ANCHOR - A fastener for use in concrete includes a shank and a head. The shank has a tip distal most from the head. The shank includes a first helical thread formation having a thread form thereon formed from two portions disposed upon opposite lateral sides of the thread form. The thread form has a root and the two portions include an alternating series of lobe members and base portions. The lobe members have a height as measured from the root and the base portions have a height as measured from the root. The height of the lobe members is greater than the height of the base portions and the height of the base portions is greater than zero. The fastener includes a second helical thread formation that is disposed adjacent to and spaced from the first helical thread formation. | 01-06-2011 |
