£13.14 ex. VAT £10.95

Features and Benefits:

🔩 Self-Drilling Point & Self-Tapping Thread — drills through reinforcement and taps its own thread in one pass
⏺ Countersunk Head with Ribs — ensures flush installation under hardware and enhances grip during countersinking
⚙ Zinc-Plated Finish — offers corrosion resistance in general environments
🏗 Designed for Reinforced Frames — ideal for frames with steel or aluminium reinforcement present
🛠 Versatile Hardware Use — suitable for hinges, locks, brackets, glazing, and general window frame installation

Description:
These window fabrication screws are built for reliable fastening in windows and doors with internal reinforcement. The self-drilling point allows penetration into steel or aluminium without pre-drilling, while the self-tapping thread secures materials firmly. The countersunk head features ribs under the head to improve countersinking and ensure a flush, clean finish under mounted hardware. With a zinc-plated coating, these screws are protected against oxidation in many interior and exterior environments. Ideal for use in frame fabrication, glazing, locking hardware, and general window construction. According to supplier sources, they are used in frames where steel or aluminium reinforcement is present.
