Installation & Usage

1. Select appropriate hex driver or impact tool for 5/16" indented hex head engagement
2. Position screw perpendicular to work surface ensuring proper alignment for straight penetration
3. Apply steady downward pressure while engaging drill point to initiate drilling through material
4. Maintain consistent speed and pressure as drill point creates pilot hole and threads engage
5. Continue driving until integrated washer contacts surface, distributing load evenly
6. Verify final torque does not exceed torsional strength rating of 61 lb-in minimum for optimal joint integrity
