PEEK Low Hex Socket-Cylinder Head Cap Metric Screw - DIN 7984

SKU: PKLH306
Regular price $1.86 inc. VAT

PEEK Low Hex Socket Cylinder Head Cap Metric Screws manufactured to DIN 7984 standards are premium engineering fasteners designed for applications requiring exceptional mechanical strength, chemical resistance, and high-temperature performance. Manufactured from Polyether Ether Ketone (PEEK), these screws provide a lightweight, corrosion-resistant alternative to metal fasteners while maintaining outstanding performance in demanding operating environments.

Featuring a low-profile cylinder head in accordance with DIN 7984, these fasteners are ideal for compact assemblies where installation space is limited. The internal hex socket allows secure tightening and efficient torque transfer, making these screws suitable for precision equipment and repeatable assembly processes. PEEK exhibits outstanding resistance to aggressive chemicals, hydrolysis, wear, and radiation while retaining its mechanical properties at elevated temperatures, ensuring long-term reliability in critical applications.

PEEK low head cap screws are widely used in aerospace systems, semiconductor equipment, medical devices, electronics, chemical processing machinery, and high-performance industrial assemblies where dimensional stability, electrical insulation, and corrosion resistance are essential.
