Fastening Hardware Used with ACM
Despite standoff choices being limited, the possibilities are quite endless with fastening hardware such as rivets and self-tapping screws.
Many different types of rivets can be used with ACM. All that is required are two through holes that line up and the proper diameter and length rivet for the application. If need be, the hole can be countersunk to accept a flush head rivet.
Any type of self-tapping screw can be used with ACM. The threads of the screw will bite mostly into the polyethylene core of the material versus the thin .012 or .008 layer of aluminum facer.
