Abstract: An expansion dowel assembly is made up of an axially elongated generally cylindrically shaped dowel body and at least one wedge-shaped expansion member formed monolithically with the dowel body. The dowel body has a first or leading end which is inserted first into a borehole within which the dowel body is to be anchored and an opposite second end. A severable web connects the expansion member to the first end of the dowel body. Before insertion into a borehole, the expansion member projects outwardly from the exterior surface of the dowel body. When the expansion dowel assembly is inserted into a borehole, the web is broken and the expansion member, now separated from the dowel body, is displaced away from the first end within a wedge-shaped recess in the exterior surface of the dowel body.

Abstract: A one-piece molded plastic reusable internally threaded anchor nut removably insertable in a mounting hole in a workpiece and adapted to receive a screw comprises two sections which are joined together by an integrally formed web or hinge. When the sections are folded together, they define an internally threaded screw-receiving passage and an external releasable locking mechanism for securing the anchor nut in the mounting hole. In one embodiment the portions defining the screw-receiving passage are bifurcated and expand outwardly as the screw is inserted so as to cause the external locking mechanism (i.e., in the form of slots on the exterior of the bifurcations) to engage the edge of the mounting hole in which the nut was previously inserted. In other embodiments, the external locking mechanism (i.e.
Abstract: The present invention relates to improvements in a self-bonding fastener and to a novel method of curing the bonding material during assembly line fabrication of sheet metal products. The fastener includes a headed self-threading screw member having its head undersurface formed with an annular axially extending lip. An upper portion of the screw thread is precoated with a thermo-setting adhesive which, when heated, will uniformly bond the fastener to a sheet metal plate. As the fastener is threaded through an undersized hole in a sheet metal member, such as an automobile body, the adhesive reliquifies and is stripped from the screw thread. The adhesive is then re-deposited uniformly to completely fill a closed chamber defined between the head undersurface and the opposed sheet metal surface sealed on its periphery by the annular lip which defines the axial dimension of the adhesive thickness.
Abstract: A locking device for securing at least two screw-action connectors comprises a locking clip or element made from a good quality spring steel wire having a round or square section. The locking clip or element has a diagonal interconnecting part which extends tangentially between a pair of locking elements one at each end of the part. The locking elements (for example, coils) are wrapped round or placed over a portion of a wheel nut. The interference/friction fit between the wheel nut and the clip or element prevents axial movement of the clip relative to the nut. The part serves as restraining means positively linking tangentially adjacent wheel nuts and thereby prevents relative rotation thereof.
