WebbThe carbide coating thickness is limited to .005 (0,125 mm) per side or .010 (0.25 mm) overall. Extrusion productivity is especially sensitive to adhesive screw outside diameter wear. Doubling the screw to barrel clearance can reduce output and melt rates by as much as 25% in low viscosity resins. WebbScrews electro Nickel plated are initially copper plated, and the Nickel coat is electrolytically applied to the copper finish. Used in fasteners for electrical appliances and areas of condensation. Decorative applications account for about the vast majority of the nickel consumed by electroplating
