threade2_photo2_caseID187A cylindrical zinc pressure diecast component with an internally die cast thread. The function is to tighten the fitting on to the hose. Zinc Alloy No. 3 was chosen because of its stiffness and bright finish which is unaffected by ultra violet light. Special techniques have been developed to diecast the internal thread. This eliminates secondary operations, eliminates swarf, and makes a much stronger thread without surface porosity.
