A support foot is mechanically fastened to an information handling system chassis with a coupling device partially embedded in the support foot through injection molding of the support foot over the coupling device. For instance the coupling device is a staple made of ductile metal having a body embedded in the support foot and two legs extending outward towards the chassis side of the support foot. The legs insert in openings at a chassis attachment point and bend to secure the support foot to the chassis. For instance, the staple legs are formed from a ductile metal, such as brass, aluminum or steel, that is bent by hand or by a machine to a closed staple shape.
