Product Overview

The TechFast CSK/Wing No.3 Self-Drilling Screws (5.5x65mm) are professional-grade fixings specifically designed for securely fastening timber to steel in frame buildings. These advanced screws feature a self-drilling No.3 tip, capable of penetrating light gauge steel up to 5mm thick, eliminating the need for pre-drilling.

Fitted with breakaway wings, these screws create a clearance hole through timber, preventing thread engagement during drilling. The wings then shear off upon metal contact, allowing the thread to engage securely with the steel for a firm, reliable hold.

Protected with Elementech corrosion-resistant coating, these screws are salt spray tested to 1000 hours, ensuring outstanding durability in fire-resistant and high-moisture environments.
