ForgeFix TechFast Timber to Steel CSK/Wing Screws 5.5 x 40mm, Box of 100

The ForgeFix TechFast Timber to Steel CSK/Wing Screws are specially designed to securely join timber to steel frame buildings. Featuring breakaway wings, these screws create a clearance hole to prevent thread engagement with the timber during drilling. Once the wings contact the metal surface, they break off, allowing the thread to engage with the metal for a secure fastening.

These screws boast a TORX® compatible insert for maximum power transmission and improved countersinking with recessed ribs. They are fire and corrosion resistant, ensuring long-lasting durability in various environments. Additionally, they comply with all EU Safety, Health, and Environmental requirements.

Key Features:

• Breakaway wings for self-drilling through timber and steel
• TORX® drive for high torque application
• Fire and corrosion resistant
• Improved countersinking for flush finishes
• Self-drilling up to 5mm heavy gauge steel

Ideal for construction and carpentry applications, these screws provide a strong, secure, and efficient fastening solution for timber-to-steel connections.
