Description

Timco heavy section self-drilling screws are built for fastening metal into heavy section steel up to 12mm thick without the need to pre-drill. The hardened self-drilling point cuts through steel efficiently, helping speed up installation and making them a practical choice for demanding site work.

Designed with a hex head for secure driving and improved torque transfer, these screws are well suited to steel construction, metal framework and general metal-to-metal fixing. The bright zinc finish makes them ideal for internal and dry environments where a strong, cost-effective fixing is required.

These screws are a reliable option when sealing is not needed and a straightforward heavy duty steel fixing is the priority. They are widely used across construction and fabrication work where speed, strength and ease of installation matter.

Key Features:

  • Self-drilling point for fixing into heavy section steel up to 12mm
  • No pre-drilling required in the correct application
  • Hex head for strong drive engagement
  • Bright zinc finish for internal and dry environments
  • Suitable for metal-to-metal fixing and steel construction work
  • Ideal where a sealing washer is not required
