Abstract: A grommet (200, 300, 400), a stud (102), an assembly of a grommet and a stud forming a fastener (100), and a method of assembling a grommet and a stud to form a fastener has the grommet with an interengaging element (250) in a channel wall of the grommet for engaging a cooperating, compatible or complementary interengaging element in a wall of the stud. The grommet and the stud can be assembled by moving the grommet and the stud relative to each other until the interengaging element in the grommet engages the complementary interengaging element in the stud. A family of grommets is described.

Abstract: A tie wrap anchor assembly and methods of assembly include a body member having an internal passageway and an outwardly extending structure. A fastener element includes a first threaded end portion, a second end portion and a flange member between the first and second end portions. A cylindrical member is configured to extend within the internal passageway and receive at one end the fastener element for positioning the body member between the flange member on the fastener element and a laterally extending element on the cylindrical member. In one configuration, the body member is freely pivotable relative to the cylindrical member, and in one configuration the cylindrical member has a head with a plurality of surfaces that can be used to turn the cylindrical member.

Abstract: A fastener is formed monolithically, or as a one-piece structure, for example 100% plastic. The fastener includes a body having first and second portions on respective sides of a positioning wall or stop means. A first portion includes a plurality of compressible retention surfaces separated from adjacent retention surfaces by a corresponding conical structure and a cylindrical surface on the body. A second portion includes a plurality of resiliently flexible tongues spaced apart from each other. The tongues may be positioned on opposite sides of the body from each other, and/or at different axial positions along the body.

Abstract: Panel fasteners, panel assemblies, methods of assembly and installation of panel assemblies and panel fasteners, anchor systems, anchor systems with captive fasteners and assemblies are disclosed.

Abstract: A nut assembly and a holddown assembly using the nut assembly are described, including methods of manufacture and assembly. The nut assembly may include a body portion having first and second openings with an internal wall extending between them. A rotation-inhibiting wall may be included between the first and second openings. A nut portion configured to move axially within the internal wall of the body portion includes structures for co-acting with a rotation-inhibiting wall to limit or prevent rotation of the body portion and the nut portion relative to each other. A nut portion and a body portion extending around the nut portion have limited axial movement relative to each other due to axial engagement between adjacent surfaces on the nut portion and the body portion.

Abstract: Fastener assemblies, elements for fastener assemblies and methods of making and assembling elements for fastener assemblies, for example for insulation blanket fasteners such as those used on aircraft, may include a formed monolithic metal configuration having first and second side portions with a plurality of panel retaining elements arranged linearly along the side portions. A planar retaining element, for example a disc, may be assembled with the metal portion to form a fastener assembly, such as may be used to retain and insulation blanket. The planar retaining element may include a rolled edge, and if a coated part, may include surface projections to keep adjacent parts from sticking together during the coating process.

Abstract: A nut plate assembly and a method for securing a nut plate assembly may include a support for a fastener element wherein the support has a base to be supported and/or fixed on a support surface and the base has another surface against which the fastener element bears. The base also supports a structure for supporting the fastener element where the structure is at least partly non-symmetrical about a plane other than a horizontal plane parallel to the base. One side of the base may be secured to the support surface and the other side of the base may have the fastener element bearing against it when a complementary fastener element is secured to the first fastener element.

Abstract: Methods relating to and apparatus such as floating nut plates may include complementary surfaces limiting movement of a retainer toward or away from side walls of a receiver, such as wherein a nut element is positioned between the retainer and the receiver. One of the complementary surfaces may be a groove formed in the retainer. In one configuration, the receiver and/or retainer are non-metal.

Abstract: Fasteners such as clip nut fasteners can include a clip having a nut cage and a nut supported by the nut cage. The nut cage can have a wall supporting a portion of the nut wherein the wall can flex toward and away from the nut. The nut can have projections or other discontinuities for engaging bearing surfaces in the nut cage, for limiting rotation of the nut when under torque.

Abstract: Fasteners, fastener components and fastener receptacles, including quarter-turn fasteners may use a receptacle body having a non-metal material and one or more fastener engagement structures that together define a non-circular passage in the body. Underneath the fastener engagement structures, one or more support structures extend inwardly under the corresponding fastener engagement structures for supporting the underside of the fastener engagement structures. The support structures can have a concave configuration relative to an axis of the body. Additionally, a support structure can be co-extensive with the corresponding fastener engagement structure.

Abstract: A clip nut is provided having a plastic body holding captive a nut. The body includes two aligned arms projecting from an aft section, each arm defining an aperture at a forward portion of the arm. The nut includes a base and a upstanding portion extending from the base that defines an internally threaded bore. The body further includes a nut cage positioned disposed about the aperture of the first arm. The nut cage includes an upper wall spaced above the first arm that defines a slot having a narrowed inlet and a recess aligned with the apertures of the first and second arms. The body is configured to readily and securely receive the nut. To insert the nut into the cage, the nut is forced against the nut cage such that the upstanding portion presses into and past the narrowed inlet. In this manner, the cage yieldably receives the nut without undue manipulation of either piece.

Abstract: A quick connect fastener wherein the receptacle is adjustable to allow different stud types to be used and wherein absolute clamp-up is provided through repeated cycling. A spring loaded lock plate that captivates the quarter turn cross-pin in the locked position against the adjacent cam surface is provided. The lock plate is positioned within the receptacle and indicates the correct locked position at absolute clamp-up when the lock plate snaps over the cross-pin. Two ramps on the lockplate provide a positive “feel” when installing or removing the stud and provide the detent/lock feature. The cam comprises two helixed ramps leading to flat surfaces or plateaus for the cross-pin to ride up and tighten against. The plateaus are adjacent to detent recesses on the lock plate which provide the locking capability.

Abstract: A clip-on nut for enabling a panel to be secured to a support structure, the clip-on nut being secured to the support structure. The clip-on nut has a portion for guiding the clip-on nut into an aperture formed on the support structure, the guide portion comprising a spherically rounded projection.
