Abstract
A one-piece sheet metal insert for use in anchorage and fastening applications. The insert is designed to provide sufficient resistance to axial pull-out loading when utilized in relatively soft material workpieces such as structural foam plastic. The insert is also configured to take the clamp load between its collar and internal thread ribs thereby preventing tensile and compressive forces from being applied to the workpiece material surrounding the insert which commonly cause creep to occur.
