PPS Slotted Set Screw
PPS slotted flat point set screw is a high-performance engineering plastic fastening component designed for precision locking, adjustment, and positioning in industrial assemblies. The PPS slotted set screw is manufactured from polyphenylene sulfide (PPS), a high-performance thermoplastic known for excellent heat resistance, chemical stability, and dimensional reliability.
The PPS slotted set screw features a headless (grub screw) design with a flat point end and slotted drive, allowing controlled pressure distribution and secure positioning without damaging mating components. It is widely used in automotive electronics, electrical systems, industrial equipment, and precision assemblies where metal fasteners may cause corrosion, conductivity, or magnetic interference.
Product Overview
The PPS slotted flat point set screw is engineered for internal fastening applications requiring stable locking force and repeatable adjustment performance. Its flat point design provides a larger contact area compared to cone point or cup point variants, reducing surface damage while maintaining reliable positioning.
This PPS slotted set screw performs consistently in high-temperature and chemically aggressive environments. Unlike metal set screws, it eliminates corrosion risks and electrical conductivity issues, making it suitable for sensitive electronic and industrial systems.
As a specialized industrial fastener, it is widely used in OEM manufacturing where lightweight, non-metallic, and cost-efficient fastening solutions are required.
