| 20090245970 | Flush Captive Screw with Retractable Knurled Knob - A mounting device for a screw including a head and a tip, the mounting device comprising a body and a plunger. The body is attachable to the head of the screw, and the plunger is adapted to extend from within the body upon receiving a downward force. Additionally, the plunger includes a plurality of knurls adapted to transfer torque to the tip of the screw. | 10-01-2009 |
| 20130034406 | VIBRATION-ISOLATING SCREW - A vibration-isolating screw is disclosed. The vibration-isolating screw includes a screw head and a screw tail portion. The screw head includes a first screw body, a first magnetic element, a second screw body, a second magnetic element, a third screw body and a third magnetic element. The first magnetic element and the second magnetic element are mounted on the first screw body and the second screw body, respectively. The third screw body is mounted between the first screw body and the second screw body. The third magnetic element comprises a first end and a second end and is mounted on the third screw body. The first end and the first magnetic element are adjacent and mutual repulsion. The second end and the second magnetic element are adjacent and mutual repulsion. The screw tail portion is connected with the second screw body. | 02-07-2013 |
| 20140023456 | Armor Bolts - An armor bolt, that is, a bolt in which the bolt head is fabricated from an armor plate and then attached, such as by welding, to a threaded stud or shaft to form the threaded portion of the armor bolt. A preferred embodiment of the invention employs a hex-shaped bolt head cut with a laser or water jet cutter from armor steel plate meeting Mil-A-12560 or Mil-A-46100. The diameter of the bolt head is determined by the hole size in the armor to be attached to the vehicle and the diameter of the threaded stud or shaft. The thickness or height of the bolt head is dictated by the ballistic threat it needs to stop. The threaded shaft in a preferred embodiment is resistance welded to be perpendicular to the head at the center of one face of the hex head. | 01-23-2014 |

| 20100183401 | DEVICE FOR FASTENING SUPERIMPOSED ELEMENTS - The present invention relates to a device for fastening two elements to one another, comprising a rod-like member having opposite ends which are aligned on a common longitudinal axis (X-X) and a threaded portion formed in the region of a first end. A characteristic of the rod-like member is that it comprises a tapered portion formed in the external wall of the rod-like member, the tapered portion having the vertex of its taper facing towards the threaded portion and a taper angle (α), measured relative to the longitudinal axis (X-X), that is within a range variable between 2° and 6°. | 07-22-2010 |
| 20100278613 | FIXED EYEBOLT ASSEMBLY AND INVENTORY THEREOF - An eyebolt assembly is provided in which a skirt member is reinforced by radially projecting diametrically extending ribs. A fixed lifting eye projects from one side of the skirt, and a mounting stud projects from the opposite side. The mounting stud is double threaded with one thread being adapted to mate with a threaded bore in the body of the eyebolt assembly, and the other thread being matched to a threaded bore in a load. The same eyebolt body can be employed with a plurality of different mounting studs, which simplifies inventorying eyebolt assemblies to meet all of the different threaded bores that may occur in different loads. Only the mounting studs need to be threaded to match the loads. The skirts are provided with striking faces so that they can be tightened and loosened by striking them with a hammer. | 11-04-2010 |
| 20110170986 | Threaded Stud With Locking Pawl - A threaded fastener-nut combination for attaching two work pieces together has means for preventing the intrusion of the fastener threads into the bores of each work piece, thus preventing damage to the work piece which may result from such intrusion. The stud member has a pawl member which extends radially outward to engage an aperture in the nut member, which locks the nut member to the stud member. The engagement of the nut member to the threaded portion of the stud member produces both audible and tactile feedback to indicate that the fastener is properly placed and engaged. Tactile feedback is returned through the emergence of the pawl through the aperture in the nut, and by the rotation of the entire fastener assembly upon the provision of further tightening effort. Auditory feedback is provided through a “click” or similar sound produced when the pawls engages the aperture of the nut. | 07-14-2011 |
| 20130017036 | SCREW STRUCTUREAANM CHEN; Yun-LungAACI Tu-ChengAACO TWAAGP CHEN; Yun-Lung Tu-Cheng TWAANM SHU; XianAACI Wuhan CityAACO CNAAGP SHU; Xian Wuhan City CN - A screw structure for securing a first object to a second object comprises a screw member, a blocking member and a pivot member. The screw member comprises a pole. The blocking member comprises a base portion secured to the pole, and two positioning portions are located on the base portion. The pivot member comprises two latching portions, and each of the two latching portions is engaged between the screw member and each of the two positioning portions. The pivot member is capable of rotation relative to the screw member and the blocking member. | 01-17-2013 |
| 20140056669 | CONCRETE BOLT ASSEMBLY - A concrete bolt assembly comprises a bolt set and a spherical washer for the bolt set to penetrate. The bolt set includes a concrete bolt member and a spherical nut disposed on the concrete bolt member. The spherical nut has a first sphere and the spherical washer has a second sphere. With the arrangement of the first sphere and the second sphere, the concrete bolt assembly can be embedded in a building material from any inclined angle since the contact of the spherical nut and the spherical washer exerts a perpendicular force to densely tighten the concrete bolt assembly, prevent the embedded concrete bolt assembly from easily corning off or extracting front the building material after screwing, and enhance an engaging effect of the assembly. | 02-27-2014 |
| 20150369272 | THERMALLY-ISOLATING FASTENER - A thermally-isolating fastener for use in a cavity wall to connect a wall anchor to an inner wythe includes a fastener shaft having a screw portion including a driven end and an attachment portion opposite the driven end. A fastener head is selectively attachable to the attachment portion of the fastener shaft. The fastener head includes an internal portion and an external portion encasing the internal portion. The external portion is configured to provide a thermal break in the cavity wall when installed. | 12-24-2015 |
