Polycarbonate Hexagon Socket Grub Metric Screws manufactured to ISO 4026 standards are durable, lightweight fastening components designed for applications requiring electrical insulation, corrosion resistance, and reliable mechanical performance. Manufactured from high-quality Polycarbonate (PC), these set screws provide a non-metallic alternative to traditional metal grub screws in environments where conductivity, corrosion, or weight reduction are concerns.
Featuring an internal hexagon socket drive and flat point design, these screws are ideal for securing components without protruding beyond the surface of the assembly. Polycarbonate grub screws are commonly used in electrical equipment, instrumentation, laboratory devices, automation systems, and precision assemblies where nonconductive fastening solutions are required.
Known for its excellent impact resistance and dimensional stability, Polycarbonate maintains reliable performance under mechanical stress while resisting moisture and environmental exposure.
