The Forgefix TechFast Composite Panels to Steel Hex Screws are professional-grade fasteners designed for contractors and builders tasked with mounting composite panels to heavy-gauge steel structures. These screws offer a reliable, secure connection with integrated compression control to protect panel surfaces; however, users should ensure they are using the correct drill tip rating for their specific steel thickness to prevent slippage or snapping.

No, these screws are specifically designed for composite panels to steel frame applications and feature drill tips optimized for metal.
The No.5 drill tip is rated for heavy gauge steel up to 12.5mm.
No, the TechFast No.5 drill tip is designed for self-drilling into steel, eliminating the need for a separate pilot hole.
Yes, they feature an Elementech corrosion-resistant coating that is salt spray tested to 1000 hours, making them highly durable in harsh conditions.
This specific screw model is designed for insulation thicknesses ranging from 32mm to 70mm.
Verify the steel thickness does not exceed 12.5mm and ensure the drill bit is not dulled.
Reduce the torque on your drill and ensure the tool is set to a slower speed to allow the compression thread to function properly.
Check that the EPDM washer is properly seated and not distorted by over-tightening.
To ensure the longevity of your installation, use a magnetic hex driver socket compatible with the screw head size. When drilling into steel, apply steady, firm pressure perpendicular to the surface. Avoid using impact drivers if possible, as they can sometimes damage the screw thread or cause the drill point to wander. These screws are designed for insulation thicknesses between 32mm and 70mm. Once installed, inspect the EPDM washer to ensure it has seated flush against the panel surface. No specific maintenance is required, though standard visual inspections of the cladding panels for loose fasteners are recommended annually.
