ABSTRACT:
An improved fastener includes a shank section which is coaxial with and extends outwardly from a head section. The head section has a rim which cooperates with the shank section to form a groove in which sheet metal is received. The head and shank sections have arcuate indentations into which the sheet metal is forced. In addition, the shank section has arcuate outer side surfaces which oppose flat outer side surfaces on the rim. Due to the difference in the configurations of the side surfaces of the rim and shank sections, constrictions are formed between the rim and shank sections. Each constriction tends to deform or extrude sheet metal upon the application of torque to the fastener. The corners of the indentations in the shank sections and the rim apply shear forces to the sheet metal to further resist relative rotation between the fastener and the sheet metal. The indentations in the rim of the fastener have sloping side surfaces to promote a smooth flow of the sheet metal into the groove upon mounting of the fastener in the sheet metal.
