The screw is as the arrowhead hunting component for mechanical broadhead, to balance the weight, Titanium screw weight is better for weight reduction. Welcome custom the screw size for mass production.   Product details: • Material：Stainless/Titanium etc. • Surface treatment: Zinc or nickel plating OR custom • Weight tolerance: ±0.1g     The CORE TECHNOLOGIES KELU has are MIM and CNC, both for the high-end sport components. Metal injection molding (MIM) is a revolutionary technology which integrating Plastic Injection Molding, Polymer chemistry, Powder metallurgy and Metallic materials science. We can develop mold for special customized size/shape or produce by existing mold directly. Tungsten, Brass, Stainless Steel could be chosen as materials for MIM. Computer numerical control (CNC) is the automation of machine tools by means of computers executing pre-programmed sequences of machine control commands. And its applicative materials include Titanium, Tungsten, Aluminum, Brass, Stainless Steel, Zinc and so on. Main Markets： North Americam, Europe, Australia, Asia
