Abstract
In a package designed to be readily loaded into a magazine, stacked roofing washers are collated by means of an elongate, flexible, polymeric strap extending through central apertures of the washers. Near each end of the strap, the strap is formed with a formation, such as, for example, an overhand knot, which is capable of supporting the washers if the package is suspended from the other end of the strap. One such formation is capable of being deformed sufficiently so as to permit it to be forcibly pulled through the washer apertures. A related method of loading such washers into the magazine and a related method of packaging such washers are disclosed. Each such method involves the package noted above.
