Abstract: A fastening system having a T-bolt, a nut, and a washer. The T-bolt includes a bolt head having a bolt head base portion and a bolt head collar portion. The nut includes a threaded opening for engaging corresponding threads of the T-bolt shaft. The washer includes a washer base portion, a washer collar portion, and an aperture extending through the washer base portion and the washer collar portion for slidably positioning the washer around the shaft of the T-bolt between the nut and the bolt head. When the fastening system is in an installed position, the bolt head base portion engages an outer surface of a first joining member, the washer base portion engages an outer surface of a second joining member, and the bolt head collar portion and the washer collar portion both extend at least partially into an opening formed by aligned slots of the joining members.

Abstract: A fastening system for receiving an associated screw for joining parts together to form a structure. The fastening system includes a structural nut and a breakaway nut having a circumference that includes a shape that is configured to be engaged by a hand tool for rotating the breakaway nut. Upon rotation of the breakaway nut with respect to the associated screw, the structural nut is tightened against the structure to a desired tension whereupon the breakaway nut is dimensioned and configured to shear apart from the structural nut.

Abstract: A radome system includes an access panel having an upper end including an upper latch and a lower end including a lower latch. The radome system further includes a frame system including a first mounting frame positioned adjacent the upper end of the access panel and a second mounting frame positioned adjacent the lower end of the access panel. The upper end of the access panel is hindgedly connected to the first mounting frame and the lower end of the access panel is hingedly connected to the second mounting frame for hingedly connecting the access panel to the frame system. The first mounting frame includes an upper latch receiver for removably securing the upper end of the access panel to the first mounting frame, and the second mounting frame includes a lower latch receiver for removably securing the lower end of the access panel to the second mounting frame.

Abstract: A blind bolt extends through a hole which extends through a first and second member. An anchor is disposed on the distal end of a blind bolt shaft, and the anchor has expanded and contracted configurations. An anchor is disposed on the distal end on a shaft and is positioned beyond the distal end of the hole engaging a surface of the second member thereby holding the shaft in the hole. A shear sleeve is disposed on the blind bolt proximate to the distal end of the shaft and has a length sufficient to extend across the second member, across the interface between the first and second members and partially across the first member. A nut is threaded on the threads of the shaft, and a collapsible cylinder is disposed on the blind bolt shaft between the sheer sleeve and nut.

Abstract: A blind bolt and tool is used for fastening a bolt through a hole in a structure when only one side of the structure is accessible. A receiver is formed on the tip end of a bolt shaft opposite from a bolt head. Internal threads are formed within the receiver proximate an outward end, and a hex socket is formed in the inward end of the receiver. External threads and a guide are formed on a tip of the tool, and the external threads mate with the internal threads in the receiver to hold the bolt during installation. A hex key on one end of the tool engages the hex socket in the receiver so that the tool may impose a torque on the bolt when a nut is being tightened on the bolt. In another embodiment, a splined tip is formed on the end of the bolt. The tip is designed to shear off when a sufficient torque is applied. Also, a shim is configured to fit between structures held together by the blind bolt.

Abstract: An apparatus including a threaded member having a head, a shaft extending away from the head, threads disposed on at least a portion of the shaft, and a tip opposite the head. The head, tip, shaft, and threads are sized to pass through a hole in a structure such that the threaded member may be inserted into the structure. The apparatus further includes a tool for mounting to the threaded member that extends out of out the hole when the threaded member is located within the structure. The tool includes a connector that mounts to the tip of the threaded member and a flexible member that extends away from the connector and out of the hole when the threaded member is located within the structure.

Abstract: A step bolt connector and bolt assembly creates steps on a structure for accommodating a worker's boot. A first threaded bore is formed in a cylindrical end of a step bolt connector and this first threaded bore is threaded onto an exposed bolt on a structure. A sight hole extends from the exterior of the connector to the inward end of the first threaded bore for visually checking to see if the bolt is adequately attached in the first bore. A recess is formed in the cylindrical end and the recess is dimensioned to fit over fastening nut on the exposed bolt on the structure. When the first threaded bore is screwed onto the exposed bolts on the structure, the recess at least partially surrounds shields and protects the fastening nut on the exposed end of the bolt. A second threaded bore is formed in a second end (a truncated conical end) of the connector, and a step bolt is secured in the second threaded bore.

Abstract: A split nut and assembly steps for fitting the nut around an exposed portion of anchor bolt having no convenient access for conventional nuts to engage. The split nut includes first and second nut halves, and each nut half has an interior surface having a threaded half cylinder that, when aligned with the other threaded half cylinder and joined along joining surfaces, forms a threaded opening. The two half nuts may be connected by connectors that are inserted into penetrations that extend through at least a portion of both half nuts. At least one end of the penetration extends from the joining surface through the exterior surface of the half nut so that the connector may be inserted into the penetration. The exterior surface of both half nuts also include flat that, when the half nuts are joined, are dimensioned to form opposed parallel drive surfaces configured to be engaged by a wrench for screwing the split nut onto the bolt.
