ABSTRACT:
A fastener for use in the construction of pallets is provided which includes a head having a head diameter, a single elongate shank having a nominal shank diameter, and a plurality of rings extending outwardly from the shank. Each ring had a crest and a root, with the crest being located closer to the head than the root. The fastener has a bending yield strength of about 100 ksi or greater, and a length of between about 0.5 inch and 1.75 inches. The ratio of the head diameter to the nominal shank diameter is between 2.70 and 3.37, and the plurality of rings are formed so that an average outer diameter of the crests of the rings between a middle ring and the head is greater than an average outer diameter of the crests of the rings between the middle ring and the tip.
