A fastener plate is provided for use in securing together structural elements. The plate includes a base plate to which is ultrasonically welded at least one fastening element which may include, for example, an externally-threaded, stud-like fastening element, or an internally-threaded fastening element. A method for fabricating said plate is further described, said method comprising the steps of locating said at least one fastening element on said base plate and then ultrasonically welding said element to said base plate using an ultrasonic welder which includes a center aperture and which is adapted to effect a weld between the annular base portion of the fastening element and the base plate. In an alternative embodiment, at least one locking ring may be used to overlay the annular base portion with the weld being effected between the ring and the base portion.
