Features and Benefits:

• 🔩 Self-Drilling Point + Metric Thread — drills into steel or aluminium reinforcement and secures tightly without pre-drilling

• ⏺ Countersunk Facet PH Head — ensures a flush finish beneath hardware for clean, professional installation

• ⚙ Zinc-Plated Protection — resists rust and wear in general construction and fabrication environments

• 🏗 Auto-Feed Compatible — frequently used with automatic feed machines for pinning steel reinforcement in PVCu frames

• 🛠 Multi-Purpose Application — ideal for hinges, locks, brackets, and hardware on reinforced window and door frames

Description

These window fabrication screws are engineered for reliable fastening in reinforced window and door systems. The self-drilling point eliminates the need for pilot holes, while the PH metric thread ensures secure, lasting grip in steel or aluminium reinforcement. A countersunk facet head delivers a flush fit under hardware, enhancing both performance and appearance. Zinc plating provides corrosion resistance and durability in standard working conditions. Commonly used with auto-feed machines for “pinning” steel reinforcement inside PVCu profiles, these screws are trusted by window fabricators, installers, and glaziers for efficient and dependable frame assembly.
