Installation & Usage

1. Select appropriate pilot hole size or mark penetration point for direct installation into sheet metal or thin materials
2. Position screw perpendicular to work surface and apply steady downward pressure while beginning rotation
3. Drive screw using #2 Phillips driver with consistent moderate torque, allowing gimlet point to cut threads
4. Continue driving until pan head contacts work surface, ensuring proper thread engagement without over-tightening
5. Verify secure fastening by checking for proper head seating and absence of material deformation
6. For electrical applications, ensure proper grounding continuity through zinc-coated connection points
