PPS Slotted Countersunk Screw
PPS slotted countersunk screw is a high-performance engineering plastic fastener designed for industrial applications requiring excellent heat resistance, dimensional stability, and chemical resistance. The PPS slotted countersunk screw is manufactured from polyphenylene sulfide (PPS), a high-performance thermoplastic widely used in automotive, electronics, and industrial equipment.
The PPS slotted countersunk screw features a 90° flat head and slotted drive design, allowing flush installation while maintaining good mechanical stability in high-temperature and corrosive environments. It is an ideal alternative to metal fasteners in applications where electrical insulation, corrosion resistance, and lightweight performance are required.
Product Overview
The PPS slotted countersunk screw is engineered for demanding environments where conventional plastics or metal fasteners may fail due to heat, chemicals, or electrical constraints. Its countersunk head design ensures a smooth surface finish after installation, improving safety and assembly compactness.
This PPS slotted countersunk screw offers excellent resistance to heat deformation and chemical attack, making it suitable for continuous-use industrial environments. Unlike metal screws, it does not rust, conduct electricity, or suffer from galvanic corrosion.
As a specialized industrial fastener, it is widely used in OEM manufacturing, automotive electronics, and precision equipment where stability and cost efficiency are important.
