ABSTRACT:
A pipe hanger strap assembly is formed having two overlapping segments with coaxial holes to accommodate the passage of a composite hanger ring nut and a pipe hanger rod. The ring nut is a composite of a tubular plastic element having a radially extending flange on one end with a metal nut embedded in the flange. A flange on one end of the overlapping segment of the pipe hanger assembly is spring-loaded against the ring nut flange by virtue of the spring constant of the formed pipe hanger assembly. This spring loaded flange contact inhibits unintentional loosening of the composite ring nut and, in the event that the plastic ring nut flange disintegrates, the flange on the overlapping segment contacts the metal nut to prevent inadvertent loosening of that nut.
