threade2_photo2_caseID187This product is a cylindrical zinc pressure die cast component with an internally die cast thread that functions to tighten the fitting on an outdoor water hose. Zinc alloy no. 3 was chosen because of its stiffness and bright finish that is unaffected by ultraviolet light. Special techniques have been developed to die cast the internal thread. This eliminates secondary operations, greatly reduces swarf, and makes a much stronger thread without surface porosity.
