PTFE Teflon Hex Head Metric Screw - ISO 4017

PTFE Teflon Hex Head Metric Screws manufactured to ISO 4017 standards are high-purity fluoropolymer fasteners designed for applications requiring exceptional chemical resistance, electrical insulation, and low-friction performance. Manufactured from high-quality PTFE, these screws provide a corrosion-free fastening solution for environments where metal fasteners may degrade, contaminate processes, or conduct electricity.

The hex head design enables secure installation using standard spanners and sockets, providing reliable fastening while maintaining the unique benefits of PTFE. With outstanding resistance to acids, alkalis, solvents, moisture, and UV exposure, PTFE hex head screws are widely used in chemical processing equipment, semiconductor manufacturing, laboratory systems, medical devices, food processing equipment, and high-purity industrial applications.

Naturally non-stick and self-lubricating, PTFE helps reduce friction during assembly while offering excellent resistance to environmental degradation. These properties make PTFE hex head screws an ideal choice for demanding applications where chemical compatibility and long-term reliability are critical.
