PEEK Hex Head Inch Screws manufactured to ASME B18.2.1 standards are high-performance engineering fasteners designed for applications requiring exceptional mechanical strength, chemical resistance, and thermal stability. Produced from advanced Polyether Ether Ketone (PEEK), these screws combine excellent strength-to-weight characteristics with outstanding resistance to corrosion, wear, and aggressive chemicals, making them ideal for demanding industrial and high-performance applications.
Produced with Unified National Coarse (UNC) threads, these fasteners are designed for inch-based assemblies and provide reliable fastening in applications where strength, precision, and long-term durability are essential. The hex head design allows for secure installation using standard spanners and sockets, enabling high torque transmission and dependable clamping force. PEEK hex head screws are widely used in aerospace systems, semiconductor manufacturing equipment, medical devices, electronics, chemical processing machinery, and high-performance industrial applications.
PEEK offers exceptional resistance to aggressive chemicals, hydrolysis, wear, and radiation while maintaining its mechanical properties at elevated temperatures. Combined with low moisture absorption and excellent dimensional stability, these screws provide reliable performance in critical environments where conventional plastic or metal fasteners may be unsuitable.
