Frequently Asked Questions
What is a self-drilling cladding screw?
A self-drilling screw (also called a "tek screw") has a drill-point tip that cuts through the substrate without a pre-drilled hole, making installation faster on steel and composite structures.
Are TechFast screws suitable for steel cladding?
Yes — TechFast self-drilling screws are designed to fix through cladding panels directly into light-gauge steel purlins and rails. Check the point number (e.g. Point 3 or Point 5) for compatibility with the steel thickness.
