3.9 x 25mm Window Fabrication Screws - Countersunk - Self-Drilling Point - Yellow (Box Of 1000) - 123Y

£13.73 ex. VAT £11.44

Features and Benefits:

🔧 Self-Drilling Tip + Self-Tapping Thread — drills through steel/aluminium reinforcement while cutting its own threads
⏺ Countersunk PH Head with Ribs — ensures flush mounting under hardware and secure grip
💛 Yellow Passivated Finish — corrosion-resistant yellow coating blends with window fittings
🏗 Ideal for Reinforced Frames — designed for use where steel or aluminium reinforcement exists
⚙ Versatile Application — perfect for window, door, glazing, uPVC frame hardware installation

Description:
These window fabrication screws are engineered to handle the demands of fastening hardware to reinforced frames. The self-drilling point eliminates the need for pre-drilling, while the self-tapping thread secures materials directly into steel or aluminium reinforcement. The countersunk PH head with ribs sits flush and ensures a clean, secure finish. A yellow passivated coating provides added corrosion resistance and aesthetic consistency for window systems. Ideal for contractors, fabricators, and installers fitting hardware into PVC, uPVC, metal, or composite frames with internal reinforcement.
