Download the Polyphenylene Sulphide (PPS)
PPS Hex Head Metric Screws manufactured to ISO 4017 standards are high-performance engineering fasteners designed for applications requiring excellent chemical resistance, dimensional stability, and elevated temperature performance. Manufactured from Polyphenylene Sulfide (PPS), these screws provide a lightweight, corrosion-resistant alternative to metal fasteners while maintaining reliable mechanical properties in demanding environments. PPS offers exceptional resistance to a wide range of chemicals, very low moisture absorption, excellent electrical insulation properties, and outstanding resistance to creep and deformation under load. The material also retains its strength and stiffness at elevated temperatures, exhibits inherent flame resistance, and provides excellent long-term dimensional stability, making it ideal for precision assemblies operating in harsh industrial conditions.
The hex head design enables secure installation and higher torque transmission using standard tools, making these screws suitable for a wide range of industrial and engineering applications. PPS hex head screws are commonly used in electrical systems, semiconductor equipment, chemical processing machinery, automotive components, pumps, valves, and industrial equipment exposed to heat, moisture, and aggressive chemicals.
With low moisture absorption, excellent rigidity, and outstanding resistance to corrosive media, PPS fasteners deliver long-term reliability while helping to reduce maintenance and corrosion-related failures.
