PEEK Grub Screw
PEEK grub screw is a high-performance non-metallic fastening component designed for precision adjustment, locking, and positioning applications in advanced industrial assemblies. The PEEK grub screw is manufactured from polyether ether ketone (PEEK), a premium engineering thermoplastic known for excellent chemical resistance, electrical insulation, and high-temperature stability.
The PEEK grub screw (also called a set screw) has no external head and is fully threaded, allowing it to be installed flush or recessed within a tapped hole. It is widely used in semiconductor equipment, medical devices, electronics, and precision instrumentation where metal fasteners may cause corrosion, magnetic interference, or electrical conductivity issues.
Product Overview
The PEEK grub screw is engineered for applications requiring secure internal fastening without protruding heads. It is commonly used for locking components in place, adjusting mechanical positions, and securing delicate assemblies.
This PEEK grub screw performs exceptionally well in corrosive, high-temperature, and electrically sensitive environments. Unlike metal set screws, it eliminates risks of rust, galvanic corrosion, and electrical shorting, making it ideal for high-end engineering systems.
As a specialized industrial fastener, it supports OEM manufacturers who require lightweight, non-conductive, and chemically stable fastening solutions.
