Abstract
A fastener (10) including a sleeve (14) having an elongated portion (15), a head with a bearing surface (19), and an internal threaded portion (21), a core bolt (12) disposed within the sleeve (14) and having a head and a shank portion having an external threaded portion engageable threadeadly with the threaded portion of the sleeve (14). An insert (48) is disposed within the sleeve (14) and surrounds a portion of the core bolt (12). A seal element (38) is attached to the sleeve (14) and juxtaposed with the bearing surface (19) of the head of the sleeve (14). The fastener (10) is adapted to be installed in a structure. The electrical contact of the fastener (10) reduces the potential difference between it and the structure, which provides a direct path for continuous propagation of electromagnetic waves, reducing electromagnetic wave scattering and minimizing the electromagnetic signature.

Abstract
A pin member for a fastener includes an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the bearing surface of the head, and a threaded portion located at the second end of the elongated shank. The pin member can be fully coated with a coating. A conformable seal element is attached to the pin member, which is adapted to fill the microscopic voids between the bearing surface of the head of the pin member and the surrounding structure under the axial load exerted by the fastener during installation. The seal element can be separate and distinct from the pin member. The seal element can be attached to the pin member for the sake of convenience, but the seal element can deform independently of the pin member and the surrounding structure in response to the forces exerted by the fastener.

Abstract
An apparatus and method for fastening layers of non-ferrous alloys, like aluminum, magnesium and copper utilizes a steel fastener and a spot welding machine. The fastener and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the fastener to penetrate the aluminum. A weld zone between the fastener and the various layers creates an internal weld. The fastener has a rough shaft that is coated by the molten weld zone and is hard to withdraw on solidification. Layers of non-conductive materials like plastics and ceramics may also be affixed to a conductive layer using a fastener made from a compatible material that extends through a pilot hole and welds to or penetrates a conductive layer. The fastener may have projections that initially reduce contact area with the stack.

Abstract
An apparatus and method for fastening dissimilar electrically conductive materials using electrical resistance welding. A first and second material are placed together in physical and electrical contact. An electrically conductive fastener is placed in contact with the first material to form an electrically conductive stack, including the fastener, first material and second material. The first material has a lower melting point than both the second material and the fastener. A sealant is applied between the fastener and the first material. An electrical potential is applied across the stack of materials, inducing a current to flow through the stack and cause resistive heating. The resistive heating softens the first material. The fastener is urged through the first material toward the second material. After the fastener contacts the second material, the fastener welds to the second material.

Abstract
A rivet (10) includes a pin member (12) having a head (34) and a lock groove (26), and a lock ring (14) having a flange (53). The flange (53) of the lock ring (14) is swaged into the lock groove (26) of the pin member (12) and transformed to a bead (54) that engages the lock groove (26), and a portion (P) of an outer surface (50) of the lock ring (14) deforms and is rotated inwardly. The rivet (10) is installed within a structure (56) such that the head (34) of the pin member (12) is flush with an outer surface (68) of a panel (64) and the portion (P) of the outer surface (50) of the lock ring (14) is flush with an outer surface (66) of another panel (62).

Abstract
An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a steel rivet and a spot welding machine. The rivet and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the rivet to penetrate the aluminum and weld to the steel layer. The fastener may be used to join stacks with several layers of different materials and may be used to apply a threaded socket or stud made from steel or titanium to an aluminum or magnesium alloy structure. Layers of non-conductive materials like plastic and ceramics may also be affixed to a conductive layer using the fastener made from a compatible material that extends through a pilot hole.

Abstract
A blind fastener (10) including a core bolt (12) having a shank (16) with a head (30) and a threaded portion (28), and a sleeve (14) having an elongated body (38) with a head (46), an internal threaded portion (50), and a tapered notch (56) formed within an exterior surface (44) thereof and defined by a tapered portion (57) having a slope and a frictional enhanced surface. The core bolt (12) is installed within the sleeve (14) such that its threaded portion (28) engages threadedly the internal threaded portion (50) of the sleeve (14). During installation of the fastener (10) within the plurality of workpieces (24a, 24b), a bulb (55) is formed on the elongated body (38) of the sleeve (14), the bulb (55) defining a portion of a bulbed portion (61 ). When a selected axial force is reached, the bulbed portion (61) separates from the elongated body (38) and engages axially the tapered portion (57) of the sleeve (14), increasing the diameter of the bulb (55) which engages a blind side (27) of one of the workpieces (24b).

Abstract
A latch (10) includes a base (12), a drive shaft (100) and cam (102), and a handle (110) attached pivotally to the drive shaft (100). The handle (110) is moveable between a closed position, a pop-up position, and an open position. A slide plate (24) is attached slidably to the base (12) and engaged with the cam (102). A swivel arm (52) is attached pivotally to the base (12) and the slide plate (24). A bolt assembly (66) is attached to the swivel arm (52), and a plunger (32) is mounted within the base (12). In its closed position, the handle (110) engages the plunger (32) to engage a switch (36) and the bolt assembly (66) engages a structure. In the handle's (110) pop-up position, the plunger (32) moves to a retracted position and disengages the switch (36). When the handle (1 10) is moved to the open position, the drive shaft (100) and cam (102) are rotated so that the slide plate (24) slides and the swivel arm (52) pivots to swing the bolt assembly (66) away from the structure.
