PEEK Slotted Cheese Head Screw
PEEK slotted cheese head screw is a high-performance engineering plastic fastener designed for precision assemblies requiring insulation, corrosion resistance, and stable mechanical performance. The PEEK slotted cheese head screw is manufactured from polyether ether ketone (PEEK), a premium high-temperature thermoplastic widely used in aerospace, semiconductor, medical, and advanced electronics industries.
The PEEK slotted cheese head screw features a cylindrical (cheese head) profile with a slotted drive, offering a larger bearing surface than pan head screws while maintaining a compact vertical profile. It is ideal for assemblies that require secure clamping without damaging delicate components.

Product Overview
The PEEK slotted cheese head screw is engineered for applications where metal fasteners are unsuitable due to weight, corrosion, or electrical conductivity issues. Its cylindrical head design provides improved contact area, distributing load evenly and reducing stress concentration on assembly surfaces.
This PEEK slotted cheese head screw is widely used in precision instruments, electronic housings, and high-end industrial systems. It performs reliably in chemically aggressive and high-temperature environments while maintaining dimensional stability.
As a specialized industrial fastener, it is a preferred choice for OEM manufacturers seeking lightweight and non-conductive fastening solutions.
