Timco's Hex Head Self-Drilling Screws provide a robust and efficient fastening solution for attaching roofing sheets to light section steel (up to 5.0mm thick) without the need for pre-drilling. Made from case & core hardened carbon steel, they offer superior strength and durability.

The self-drilling No. 3 point ensures easy and quick installation, while the hex head with an 8mm socket size allows for secure driving with standard tools. The fixed washer (12.00mm diameter) ensures a tight and secure fit, distributing load evenly to prevent material damage.
Ideal for roofing and exterior construction, these screws combine high performance, reliability, and easy application in one package. Their effective thread length of 7mm provides strong holding power, while the maximum drilling thickness of 5.0mm ensures versatility in various light steel applications.
