🛠 Durable Construction — engineered for strength in hinge, lock, and hardware installations

Description:
These window fabrication screws are designed for efficient, reliable fastening in window and door systems. The self-drilling point allows direct penetration into steel or aluminium reinforcement without pre-drilling, while the self-tapping thread ensures a secure hold. The countersunk head features ribs under the head to enhance countersinking performance and ensure a flush appearance beneath hardware. With a yellow passivated coating, these screws resist corrosion and maintain visual harmony with frame systems. Perfect for glaziers, fabricators, and installers mounting hinges, locks, brackets, or other hardware to reinforced window frames.
