Installation & Usage

1. Mark fastener locations and ensure proper alignment of components to be joined
2. Select appropriate driver tool - 5/16" hex socket or standard slotted screwdriver
3. Position screw perpendicular to work surface and apply steady downward pressure
4. Begin driving slowly to allow gimlet point to penetrate and establish thread path
5. Continue driving at moderate speed, maintaining consistent pressure to prevent thread stripping
6. Tighten to specified torque requirements, ensuring head seats flush with surface
