PC Hex Head Screw
PC hex head screw is a high-performance engineering plastic fastener made from polycarbonate (PC), designed for corrosion-free, lightweight, and electrically insulated fastening applications. The PC hex head screw features an external hexagonal head, allowing installation with standard spanners or sockets, providing stable torque transmission and easy assembly in industrial environments.
The PC hex head screw is widely used in water treatment systems, chemical equipment, electrical insulation structures, laboratory devices, and lightweight industrial assemblies where metal fasteners may cause corrosion, conductivity, or weight issues.
Product Overview
The PC hex head screw is engineered for applications requiring chemical resistance, electrical insulation, and lightweight structural performance. Its external hex head design ensures easy tightening and removal using standard tools, making it suitable for both installation and maintenance.
This PC hex head screw is commonly used in corrosive environments where acids, alkalis, and moisture are present. Polycarbonate material provides better mechanical strength and impact resistance compared to PP and PVC plastic fasteners.
As a reliable industrial plastic fastener, it is widely used in OEM manufacturing and modern corrosion-resistant engineering systems.
