    Abstract: The present invention relates generally to improvements in screw type fasteners and to novel methods of applying such fasteners to a preformed aperture in a workpiece. The embodiments of the present invention disclosed in the accompanying drawing includes a headed screw member, the entering extremity of which is encapsulated by an adhesive having the functional characteristics of a partially cured epoxy resin. Interposed between the threaded peripheral surface of the screw shank and the aforesaid adhesive is a release coating to prevent the establishment of a bond between the adhesive and the peripheral screw surface when said adhesive is completely cured or solidified within a work aperture.

    Abstract: A liquid container drain device, such as a drain device for the sump of an automotive engine. A threaded nut, into which a threaded closure plug is insertable, is carried by a blade spring secured to the container wall at at least one end. When the plug is inserted, the blade spring is loaded, and the nut drawn against the container wall opposite a drain aperture; when the plug is removed the blade spring is unloaded and acts to lift the nut away from the container wall, thus permitting the dregs of the container contents to drain away. In modifications, a portion of the container wall may be resilient instead of, or in addition to, a support for the nut.

    Abstract translation: 液体容器排放装置，例如用于汽车发动机的贮槽的排放装置。 螺纹密封塞可插入的螺纹螺母由至少一端固定到容器壁的刮板弹簧承载。 当插头插入时，叶片弹簧被装载，并且螺母被拉到容器壁上，与排水孔相对; 当插头被移除时，叶片弹簧被卸载并用于将螺母从容器壁提起，从而允许容器内容物的废液排出。 在修改中，容器壁的一部分可以是弹性的，而不是或除了用于螺母的支撑件。

    Abstract: The present invention is a welding nut which is attached to a metallic surface by either spot welding or projection welding. The welding nut includes a nut end portion and a weld end portion of a predetermined thickness. The welding nut is constructed of a low-carbon steel and has a pilot projection which depends downwardly from the nut end portion a distance at least equal to the predetermined thickness of the weld end portion. A bore extends through the nut end portion and the pilot projection. Internal threads are provided in the bore.
