Socket head cap screws that are Baked Zinc Cr3 plated and available in inch sizes are high-performance fasteners designed to provide excellent corrosion resistance and durability. The Cr3 plating refers to a chromium trivalent coating that offers superior protection against rust and oxidation while maintaining an environmentally friendly profile. Unlike the traditional hexavalent chromium (Cr6) plating, Cr3 plating is less toxic and more sustainable, making these screws a more eco-conscious choice for a variety of industries.

These screws are often made from high-strength alloy steel, which ensures reliability and sturdiness in demanding applications. The Baked Zinc Cr3 plating provides a thin but effective layer of protection, making them ideal for use in industries like automotive, aerospace, machinery, and construction. The inch size availability ensures compatibility with systems and equipment that adhere to imperial measurements, making them versatile for a wide range of applications.

The key benefits of these screws include excellent corrosion resistance, especially in harsh environments where exposure to moisture, chemicals, or salts is common. The baked zinc coating offers an aesthetically pleasing finish while enhancing the screw's overall durability. The socket head design allows for easy installation and a secure, high-torque fastening, ensuring these screws are an excellent choice for applications requiring strength, reliability, and long-term performance.
