Anti-Slip Design : The unique cup head design, combined with a cross hole, increases the contact area between the screw and the tool. This effectively prevents the screw from slipping during installation, enhancing installation efficiency and stability.

Coating : The surface is treated with a galvanized coating, forming a dense protective film. This enhances the screw's corrosion resistance, ensuring good performance in humid environments, extending service life, and giving the screw an attractive appearance.Galvanized

High-Strength Material : Made from high-quality alloy steel and processed with precision heat treatment, the screw has high strength and toughness. It can withstand significant tensile and compressive forces, meeting the fixing requirements of electric meters and other equipment in various complex situations.
