Abstract
Blind inserts for use with sandwich panels and methods for manufacturing the same. A blind insert can include a nut arranged in an insert. The insert can include a cavity at an end of the nut. When a screw is screwed into the nut, the screw can enter the cavity and dig into the insert. The interference between the insert and the screw can provide friction that prevents the screw from loosening in a vibrating environment. The blind insert can be made by placing a mandrel into the nut. The mandrel includes a nose that extends past the end of the nut. When the insert is molded around the nut, the mandrel prevents mold material from entering a threaded aperture of the nut and forms the cavity in the insert. The blind insert can also be made by placing a cap that defines the cavity on the end of the nut. The insert can be molded around the cap and the nut.
