PPS Slotted Cheese Head Screw
PPS slotted cheese head screw is a high-performance engineering plastic fastener designed for industrial applications requiring excellent heat resistance, chemical stability, and electrical insulation. The PPS slotted cheese head screw is manufactured from polyphenylene sulfide (PPS), a high-performance thermoplastic widely used in automotive, electrical, and industrial equipment systems.
The PPS slotted cheese head screw features a cylindrical (cheese head) profile with a slotted drive, providing a larger bearing surface than pan head designs while maintaining compact installation height. It is widely used in environments where metal fasteners may cause corrosion, conductivity issues, or excessive weight.

Product Overview
The PPS slotted cheese head screw is engineered for precision industrial assemblies requiring stable fastening performance under heat and chemical exposure. Its cylindrical head design increases contact area, improving load distribution and reducing stress concentration on assembled parts.
This PPS slotted cheese head screw performs reliably in high-temperature environments and chemically aggressive conditions. Unlike metal fasteners, it does not rust, conduct electricity, or generate magnetic interference, making it suitable for advanced engineering systems.
As a specialized industrial fastener, it is widely used in OEM manufacturing, automotive electronics, and precision equipment where stability, insulation, and cost efficiency are required.
