Installation & Usage

1. Mark fastener locations and ensure proper alignment with mounting holes or installation points
2. Select appropriate drive tool - 5/16" hex driver or slotted screwdriver based on access requirements
3. Position screw perpendicular to work surface and apply steady downward pressure during initial engagement
4. Drive screw at moderate speed, allowing gimlet point to penetrate and begin thread formation
5. Continue driving until head is properly seated, monitoring torque to prevent over-tightening
6. Verify secure attachment and proper thread engagement for optimal holding power
