Installation Instructions

Step 1: Place the screw vertically on the mounting surface, fit and fasten with a matched hex socket bit.

Step 2: Perform direct tapping without pre-drilling, allowing the screw to cut complete and smooth threads into the base material.

Step 3: Keep tightening the screw steadily until the screw head closely fits and presses firmly against the material surface.

Step 4: Inspect the overall installation to confirm the screw is securely fixed with no tilt or loose gap.

Installation Notes
