Buying Guide: Key Purchase Considerations

  • Included hardware: Some sets include screws and a driver; others require separate purchases. Plan accordingly.
  • Load capacity: For heavy furniture or shelves, prefer larger plates with more contact area and thicker material.
  • Installation ease: Unified screw sizes and clearly labeled parts speed up setup and reduce mistakes.
