Description
These 38mm bi metal self drilling screws fix roofing sheets directly to light section steel up to 5.0mm. Because of the hardened No.3 drill point, they cut through steel quickly and remove the need for pre-drilling.
At the same time, the A2-304 stainless steel body provides excellent corrosion resistance. This combination delivers fast drilling performance along with long-term durability. As a result, 38mm bi metal self drilling screws are ideal for roofing and external applications.
The 16mm EPDM washer compresses during installation. Therefore, it creates a watertight seal that helps prevent water ingress. In addition, the hex head design improves drive control and reduces slippage when fixing.
Key Features
- Bi-metal construction with A2-304 stainless steel body
- Hardened carbon steel No.3 drill point
- EPDM washer provides a watertight seal
- Designed for light steel up to 5.0mm
- 60° self-tapping thread for secure fixing
- Fully threaded for strong hold
- Corrosion Rating 4 for external environments
Typical Applications
- Roofing sheets to light steel
- Cladding installations
- External metal-to-metal fixing
- Construction projects exposed to the elements
These screws are manufactured for steel substrates and perform reliably in urban and industrial environments with moderate salt exposure.
