Download the Polyimide (PI)
Polyimide Vespel Metric Hexagon Nuts manufactured to ISO 4032 standards are ultra-high-performance fastening components designed for extreme environments requiring exceptional thermal stability, wear resistance, and mechanical reliability. Manufactured from Vespel polyimide, these nuts deliver outstanding performance under high temperatures, vacuum conditions, and demanding mechanical loads where conventional plastics may fail.
The standard hexagonal profile is designed for use with metric bolts, screws, threaded rods, and studs, including ISO-standard fasteners, while remaining compatible with conventional spanners and sockets for easy installation. This design provides secure fastening and even load distribution across assembled components. Vespel exhibits excellent creep resistance, low outgassing characteristics, and outstanding dimensional stability, maintaining reliable performance at temperatures up to approximately 572°F , making it ideal for precision applications operating in harsh environments.
Polyimide Vespel hex nuts are widely used in aerospace systems, semiconductor manufacturing equipment, vacuum systems, medical devices, and high-performance industrial applications where long-term reliability and thermal endurance are critical.
