Installation Instructions

Step 1: Place the screw vertically on the wooden mounting surface, fit and fasten with a matched Phillips, Pozidriv or Torx bit.

Step 2: Perform direct tapping without pre-drilling, allowing the sharp screw tip to cut smooth threads into wood, particleboard or MDF base material.

Step 3: Keep tightening the screw steadily until the countersunk head is fully flush and flat with the board surface.

Step 4: Inspect the overall installation to confirm the screw is tightly fastened with no wobble, gap or wood cracking.

Installation Notes

1. Keep the screw and tool vertical during operation to prevent screw deflection, board cracking and surface damage.

2. Avoid over-tightening to prevent thread stripping, wood splitting and excessive sinking of the screw head.

3. Adopt fully matched drive bits to prevent bit slipping, screw head damage and unstable fastening.
