PVC Phillips Countersunk Screw
PVC Phillips countersunk screw is a lightweight corrosion-resistant plastic fastener made from polyvinyl chloride (PVC), designed for flush surface installation, electrical insulation, and chemical-resistant industrial applications. The PVC Phillips countersunk screw features a 90° flat head (countersunk design) with a cross recessed drive, allowing the screw head to sit flush with the mounting surface after installation.
The PVC Phillips countersunk screw is widely used in water treatment systems, chemical equipment, electrical insulation assemblies, laboratory devices, and lightweight industrial structures where metal fasteners may cause corrosion, conductivity, or weight issues.
Product Overview
The PVC Phillips countersunk screw is engineered for applications requiring a smooth surface finish and reliable non-metallic fastening performance. Its countersunk head design ensures the screw does not protrude after installation, improving safety and aesthetics.
This PVC Phillips countersunk screw is commonly used in corrosive environments where resistance to acids, alkalis, and moisture is required. PVC material provides stable chemical performance and cost efficiency, making it suitable for large-scale industrial use.
As a reliable industrial plastic fastener, it is widely applied in OEM manufacturing and corrosion-resistant engineering systems.
