Download the Polypropylene (PP)
Polypropylene Hex Head Metric Screws manufactured to ISO 4017 standards are lightweight, corrosion-resistant fasteners designed for applications requiring chemical resistance, electrical insulation, and cost-effective performance. Manufactured from high-quality Polypropylene (PP), these screws provide a practical alternative to metal fasteners in environments exposed to moisture, chemicals, and corrosive conditions.
The hex head design allows the screw to be tightened using standard spanners or sockets, enabling greater torque to be applied than many other plastic fastener styles. This makes hex head screws particularly suitable for securing panels, housings, brackets, pipe supports, tanks, and equipment assemblies where a strong clamping force is required. Polypropylene hex head screws are commonly used in chemical processing equipment, water treatment systems, laboratory installations, food processing machinery, and general industrial applications where corrosion resistance, chemical compatibility, and nonmetallic construction are important.
Polypropylene offers excellent resistance to many acids, alkalis, and cleaning chemicals, along with low moisture absorption and good impact resistance. These properties help ensure dependable performance while eliminating concerns associated with rust, oxidation, and galvanic corrosion.
