Abstract
An all plastic spray nozzle attachment is provided to avoid corrosion problems, with a self-adjusting fastener system which minimizes or avoids bending stresses on the securement screw that joins the free ends of the two hinged clamp arms that embrace the support pipe. Both the head and nut ends of the screw and the respective abutting surfaces of the clamp arms are provided with arcuate abutment surfaces which permit rocking movement of the head and nut portions about axes generally parallel to the longitudinal axis of the support to readily maintain the head and nut in coaxial alignment with one another, thereby relieving bending stresses on the screw shank as the fastener is tightened to draw the arms toward one another into clamped position.
