PVC Socket Head Cap Screw
PVC socket head cap screw is a lightweight, corrosion-resistant engineering plastic fastener made from polyvinyl chloride (PVC), designed for chemical-resistant, insulating, and cost-effective industrial applications. The PVC socket head cap screw features a cylindrical head with an internal hex (Allen) drive, allowing high installation torque and stable fastening performance in non-metallic assembly systems.
The PVC socket head cap screw is widely used in water treatment systems, chemical equipment, laboratory devices, electrical insulation structures, and lightweight industrial assemblies where metal fasteners may cause corrosion or conductivity issues.
Product Overview
The PVC socket head cap screw is engineered for applications requiring chemical resistance, electrical insulation, and lightweight structural design. Its internal hex drive allows precise torque application using Allen keys, making it suitable for controlled assembly environments.
This PVC socket head cap screw is commonly used in corrosive environments where metal fasteners fail due to oxidation or chemical attack. The PVC material ensures stable performance in acidic and alkaline conditions while maintaining low cost.
As a reliable industrial plastic fastener, it is widely used in OEM manufacturing and corrosion-resistant engineering systems.
