Description

These Timco self drilling screws with EPDM washer are designed for fixing into light section steel while providing a secure and weather-resistant seal. The integrated washer compresses during installation to create a tight seal against the surface.

Featuring a hardened drill point, these screws drill, tap and fix in one action, eliminating the need for pre-drilling. This speeds up installation while ensuring a consistent and reliable fixing.

The bright zinc plated finish offers corrosion resistance for general construction use, while the EPDM washer helps prevent water ingress, making them suitable for external and semi-exposed applications.

Key Features

  • Integrated EPDM washer provides a watertight seal
  • Self drilling point removes the need for pilot holes
  • Designed for light section steel up to 5mm
  • Hex head for strong and controlled installation
  • Zinc plated for corrosion resistance

Typical Applications

  • Roofing sheets and cladding
  • External metal fixing
  • Sheet metal to steel applications
  • Outdoor construction projects
  • Fixing where sealing is required

Manufactured to meet BS EN 14566:2008 and classified as Fire Rating A1, ensuring consistent performance and compliance.
