Window Screws

Window screws, also termed fenestration screws, are specialized fasteners tailored for the manufacturing and installation of UPVC and aluminum window and door systems. Produced from premium carbon steel with specialized surface treatments like yellow zinc or silver coatings, these screws are designed to prevent galvanic corrosion. They include specific variants for profile reinforcement, hardware attachment, and frame installation, often featuring undercut heads for a flush, aesthetic finish.

Specifically engineered for the fenestration industry, these screws ensure structural integrity without distorting or cracking delicate profiles. They are extensively used in UPVC profile reinforcement, hardware mounting (hinges and handles), and the secure fixing of window frames to building structures.

Key Features:

• Optimized for UPVC profiles and thin-walled aluminum sections
• Undercut or flat head designs for a perfect flush finish
• Specialized coatings to prevent corrosion and match frame aesthetics
• Self-drilling and self-tapping options for high-speed production lines
• Consistent torque control to prevent profile distortion during installation
