Concrete Self-cutting Screws For Suspended Ceilings

These are specialized fasteners designed to tap into concrete without the need for plastic anchors or pre-drilling in some cases. They feature hardened steel, high-low threading, and self-cutting tips to bite into tough materials like concrete.

2. Best Types for Suspended Ceilings

For fixing suspended ceiling hangers (e.g., wire hangers, direct fix brackets, or channels) into concrete slabs, consider:

• Concrete Self-Tapping Screws (e.g., Tapcon or equivalent)
  • Usually zinc-plated or stainless steel
  • Requires pre-drilled hole (typically 4-6mm smaller than the screw)
  • Available in different lengths (e.g., 5x35mm, 6x45mm)
• Concrete Self-Drilling Screws (less common, usually for softer concrete)
  • No need for pre-drilling
  • Works in some lightweight concrete or aerated blocks
