Abstract
The present invention provides novel structures for spin weld assemblies and a method for forming same. The spin weld assemblies are formed by attaching a fastener to a plastic insert which is then attached to a plastic workpiece. The fastener can take the form of many different structures, preferably a stud or a nut. The fastener is formed with a drive for driving the fastener into a bore of the plastic insert having first and second ends. Self-tapping threads on the fastener engage the fastener with the plastic insert when the fastener is driven into the bore of the insert. The insert, having the fastener threadedly engaged thereto, is then rotated and generally axially displaced into an opening of the plastic workpiece, thereby spin welding the insert to the workpiece. The first end of the insert provides proper alignment for the insert to be spin welded into the opening as the diameter of the first end is smaller than that of the opening. The second end of the insert provides the intimate engaging contact between the insert and a wall that defines the opening when the insert is spin welded into the opening as the diameter of the second end is larger than the diameter of the opening.
