Description

Bi metal self drilling screws 55mm fix metal to heavy section steel up to 12mm thick. The self-drilling No.5 point cuts through steel efficiently, so you don’t need to pre-drill. As a result, installation is quicker and more consistent on site.

In addition, the hex head provides a strong drive and helps maintain control during fixing. The metric thread with V flutes improves cutting performance and creates a secure hold in thicker steel sections. This makes them a reliable choice for structural and fabrication work.

These bi metal self drilling screws 55mm use a bi-metal construction. The A2-304 stainless steel body resists corrosion, while the hardened carbon steel drill tip delivers the strength needed to drill into heavy gauge steel. Therefore, they are well suited to urban and industrial environments where durability is important.

  • Self-drilling No.5 point for steel up to 12mm
  • Hex head for controlled and consistent installation
  • Metric thread with V flutes for improved cutting performance
  • A2-304 stainless steel body for corrosion resistance
