PEEK fasteners manufactured to ISO 4762 deliver a unique combination of high strength, thermal endurance, and resistance to aggressive chemicals. Produced from advanced Polyether Ether Ketone (PEEK), these metric socket head cap screws are designed for environments where conventional plastics or metal fasteners may be unsuitable due to corrosion, weight, or electrical conductivity requirements.
The cylinder head profile with an internal hex socket allows precise installation and reliable clamping performance in demanding assemblies. PEEK retains its mechanical integrity across a broad temperature range and exhibits excellent creep resistance, wear characteristics, and minimal moisture absorption, making these screws well suited for use in aerospace systems, semiconductor equipment, medical devices, and chemical processing installations.
