PP Slotted Pan Head Screw (Polypropylene Slotted Cylindrical Head Screw)
PP slotted pan head screw is a lightweight engineering plastic fastener made from polypropylene (PP), designed for corrosion-free, electrically insulating, and chemically resistant fastening applications. The PP slotted pan head screw is widely used in water treatment systems, chemical equipment, laboratory instruments, electronics housings, and lightweight industrial assemblies where metal fasteners cannot be used due to corrosion or conductivity requirements.
With its slotted drive and pan head design, the PP slotted pan head screw allows easy manual installation and removal while maintaining stable fastening performance in non-metallic systems.

Product Overview
The PP slotted pan head screw is designed for low-load fastening applications requiring excellent chemical stability and electrical insulation. Its cylindrical pan head provides a larger bearing surface, reducing stress on plastic components during installation.
This PP slotted pan head screw is commonly used in corrosion-sensitive environments where traditional metal fasteners would degrade or react chemically. The slotted drive structure makes it suitable for manual assembly and maintenance operations.
As a reliable industrial plastic fastener, it is widely used in OEM production and lightweight engineering systems.
