Drill hexagonal drill tail self tapping screws, environmentally friendly color zinc plating process, uniform coating with high hardness, smooth surface without burrs, can easily drill wood, with even force and non slip wire, combined with electric tools to drill iron, saving time and effort, rust prevention, wear resistance, and deformation, durable and durable
Standard Design – Phillips pan head self drilling screw with cross recess for easy driving and secure fastening.
High Drilling Efficiency – Equipped with a sharp drill point to penetrate metal sheets directly, eliminating the need for
pre-drilling.
Material Options – Made of stainless steel, carbon steel, zinc plated or galvanized finish, ensuring high strength and corrosion resistance.
Pan Head Advantage – Wide bearing surface distributes load evenly, ideal for fastening metal to metal and metal to wood
connections.
Wide Applications – Commonly used in roofing, steel structures, construction, furniture, and industrial equipment.

Special process and characteristic advantages:

1. The surface is galvanized, with high brightness and beautiful appearance, and strong corrosion resistance (optional surface treatment processes include white zinc plating, color zinc plating, black phosphating, gray phosphating, and nickel plating).
2. Carburization and tempering treatment can achieve or exceed standard values with high surface hardness.
3. Advanced technology, low torque, and high locking performance.
The optimal drilling steel plate thickness should not exceed 6mm
