Download the Polyphenylene Sulphide (PPS)
PPS Low Hexagon Socket Cylinder Head Cap Metric Screws manufactured to ISO 14580 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.
Featuring a low-profile cylinder head in accordance with ISO 14580, these fasteners are ideal for compact assemblies where installation space is limited. The internal hexagon socket allows secure tightening and efficient torque transfer, making these screws suitable for precision equipment and repeatable assembly processes. PPS offers exceptional resistance to a wide range of chemicals, very low moisture absorption, and excellent long-term dimensional stability, ensuring reliable performance under challenging operating conditions. Compared with PEEK, PPS is generally a more cost-effective material while still delivering excellent thermal and chemical resistance for many industrial applications. Although PEEK typically provides higher mechanical strength and superior continuous service temperatures, PPS is often selected where the operating environment does not require the premium performance of PEEK, allowing designers to reduce component costs without compromising reliability. This makes PPS an attractive choice for electronics, chemical processing equipment, and precision assemblies requiring stable, corrosion-resistant, and electrically insulating fasteners.
PPS fasteners are widely used in electronics, semiconductor equipment, chemical processing systems, automotive assemblies, and industrial machinery where exposure to heat, moisture, and aggressive chemicals can compromise conventional fastening materials.
