Installation tips

• Use a hex key that matches the screw’s hex socket size for a secure grip and accurate torque.
• Pre-drill or pilot hole as appropriate for your material to prevent splitting and ensure clean threading.
• Verify the surface will sit flush after insertion to achieve the intended low-profile finish.
