Our Self Drilling Screws Six Lobe Flat #3 Point Zinc Plated & Baked 10-16 X 3 are designed for fast, reliable fastening without pre-drilling. The combination of a six-lobe drive, flat head, and a sharp #3 point delivers quick penetration and a secure, flush finish in metal-to-metal assemblies.

Key Features

• Six-lobe drive provides high torque and a secure seating with reduced cam-out
• Flat head for a flush, clean finish
• #3 point for efficient drilling into metal
• Zinc plated coating with baked finish for superior corrosion resistance and durability
• Size 10-16 x 3 for versatile applications in light to medium gauge metals
• Self drilling capability eliminates the need for pilot holes

Applications

Ideal for metal roofing, gutter assemblies, HVAC ductwork, metal cabinets, enclosures, and other sheet metal applications where quick, strong fastening is required. The combination of coating and drive makes these screws suitable for indoor and outdoor projects with exposure to moisture when used with compatible materials.

Installation Tips

• Ensure workpiece is aligned and clean to maximize bite
• Start with light pressure to engage the point, then apply steady torque for a clean hole
• Use compatible tools for six-lobe drive to prevent stripping
• Check that the coating does not flake and avoid over-tightening to preserve the finish
