Features and Benefits:

• 🛠 Self-Drilling Point + Self-Tapping Thread — penetrates steel or aluminium reinforcement and cuts its own threads in one pass

• ⏺ Countersunk PH Head with Ribs — sits flush under hardware for a neat finish

• 🔩 Heavier Gauge Zinc Finish — built for added strength where extra load bearing is required

• 🏗 Ideal for Reinforced Frames — perfect for attaching hinges, locks, and hardware to steel-reinforced window frames

• 🌧 Corrosion Protection — zinc coating provides defense against rust and weather exposure

Description:
These window fabrication screws are engineered for demanding installations involving steel or aluminium reinforced frames. With a self-drilling point, the screw will bore its own hole through reinforcement, while the self-tapping thread ensures tight fastening without pre-drilling. The countersunk PH head with ribs allows the screw to sit flush beneath hardware, offering a clean and secure mount. The heavier gauge design, combined with a durable zinc-plated finish, delivers reliable strength for critical applications such as hinge and frame fastening. Ideal for window fabricators, contractors, glaziers, and installers working with reinforced window and door systems.
