Download the Polyimide (PI)
Polyimide Vespel Hex Socket Cylinder Head Cap Metric Screws manufactured to ISO 4762 deliver exceptional performance in applications exposed to extreme temperatures, vacuum conditions, and demanding mechanical loads. Produced from advanced Vespel polyimide, these fasteners maintain strength and dimensional integrity over a broad temperature range while offering ultra-low outgassing for sensitive environments.
The hex socket cylinder head design enables secure, high-torque installation, while the material's inherent wear resistance, low creep, and excellent friction characteristics ensure long service life. Vespel screws are widely used in aerospace systems, semiconductor equipment, and other high-purity applications where conventional plastics cannot meet performance requirements.
