20080298926 | Fastener Assembly - The present invention comprises a fastener assembly and method of use for securing first and second members. The assembly comprises a linker having a first bearing surface and a stop surface substantially perpendicular to the linker and having threaded securing opening, and a fastener. The fastener has a wedge member and a securing member where the wedge member forms substantially oppositely facing wedge and jamb surfaces. Alternative embodiments of the fastener assembly are also included. | 12-04-2008 |
20100111639 | ANTIGALLING ANCHOR BOLT AND METHOD - Disclosed is an anchor bolt including a wedge having a surface with a plurality of protrusions and a sleeve in operable communication with the surface. Furthermore, the sleeve is expandably receptive to the surface. | 05-06-2010 |
20100143067 | ANCHOR BOLT AND METHOD FOR MAKING SAME - Discloses is an anchor bolt including a stud. The anchor bolt further includes a wedge in operable communication with the stud. The anchor bolt still further includes a heat treated then cold worked sleeve disposed about the stud and in operable communication with the wedge. | 06-10-2010 |
20110070048 | CRIMPED CABLE BOLT HEAD AND ASSEMBLY - A mine roof cable bolt head has a drive head, a reinforcing collar and a crimp tube. The drive head is located at one end of the cable bolt head while the crimp tube is at the other end. The reinforcing collar is located between the two ends of the cable bolt head, adjoining the drive head. A hollow shaft passes through the length of the cable bolt head from end to end. A cable can be joined to the cable bolt head by using wedges. Once the cable is joined to the cable bolt head, the crimp tube is crimped down onto the cable to provide resistance to twist and to share some of the tensile load with the wedge joint. The reinforcing collar provides additional strength in the area of the wedge joint. The cable bolt head may be made of more than one pieces. | 03-24-2011 |
20140271032 | SYSTEMS AND METHODS FOR IMPROVING BOLTED JOINTS - A mechanical fastener assembly is provided for joining two or more workpieces. The assembly includes a mechanical fastener and a slotted insert. The mechanical fastener has a shaft received within aligned bores of the workpieces. The slotted insert surrounds at least a portion of the shaft and has a body portion received within the aligned bores, while an enlarged head portion of the slotted insert is positioned outside of the bores. The mechanical fastener assembly may further include a retaining sleeve when the bores of the workpieces have different diameters. In such case, a midsection of the retaining sleeve is at least partially received within the bore having the smaller diameter, while an enlarged end section of the retaining sleeve is at least partially received within the bore having the greater diameter. The retaining sleeve may be used in combination with or independently of the slotted insert. | 09-18-2014 |
20150023759 | Fastener for Attaching Objects to Channeled Members - A fastener for attaching objects to channeled members wherein the objects have a hole extending therethrough and the channeled members have a longitudinal slot formed between projecting longitudinal walls. The fastener includes a button and a retainer. The button includes an abutment wall, an abutment surface and an axially extending slot. The retainer includes an engagement boss and a head at opposite ends of shaft. The retainer extends through the button slot. For attaching the object, the button extends through the object hole with the abutment wall adjacent the object and the abutment surface adjacent the channeled member. The retainer boss and part of the shaft extend through the longitudinal slot. The retainer is rotated for engaging the longitudinal walls with the boss. The longitudinal walls are sandwiched between the boss and the button abutment surface and the object is sandwiched between the channeled member and the button abutment wall. | 01-22-2015 |

20120039686 | WEDGE FASTENER - A wedge fastener configured for use in extreme ambient conditions includes a pin or bolt having a head and a shank with an elongate slot through the shank. The wedge fastener also includes a wedge sized so that at least a portion of the wedge may extend through the elongate slot to grip a flange between the head and the wedge. The wedge fastener also includes a locking mechanism for locking the wedge in a gripping position against the flange. In one example, the locking mechanism includes locking keys with angled ridges configured to slide in angled slots on the wedge until the locking keys engage the shank. In another example, the locking mechanism includes a jack plate attached to the wedge and adjustment screws for engaging the shank to pull the wedge through the elongate slot. | 02-16-2012 |
20120082527 | SEAT TRACK AND MONUMENT ATTACH FASTENER - A blind fastener employs a split bolt element having two symmetrical half sections split at mating separation faces and cooperatively displaceable between a first collapsed position and a second expanded position. A capture portion split bolt has a substantially circular plan form in the fist collapsed position with a diameter which is received through an attachment hole in a structural member. A bearing section and a threaded portion both have a substantially circular plan form in the second expanded position while the capture portion has compression surfaces extending with an elliptical major axis greater than the hole diameter in the extended second position to engage a bottom surface surrounding the attachment hole. The bearing section closely engages the attachment hole in the expanded position. A wedge separator element is insertable between the half sections to expand them from the first collapsed position to the second expanded position. A nut is threadably received on the threaded portion and engages a lip on a mounting aperture in a monument to be attached to the supporting structure. | 04-05-2012 |
