PEEK Metric Set Screws manufactured to ISO 4026 standards are advanced engineering fasteners developed for demanding applications where high strength, outstanding chemical resistance, and excellent thermal performance are essential. Produced from Polyether Ether Ketone (PEEK), these set screws offer a lightweight, corrosion-resistant alternative to traditional metal fasteners while delivering long-term reliability in challenging operating conditions.
Featuring an internal hexagon socket drive and flat point design, PEEK set screws are ideal for securing shafts, collars, bearings, and precision components without protruding beyond the surface of the assembly. Their combination of high strength, dimensional stability, and resistance to harsh operating conditions makes them well suited for semiconductor equipment, medical devices, aerospace systems, electronics, and chemical processing applications.
PEEK retains its mechanical properties at elevated temperatures and offers outstanding resistance to chemicals, hydrolysis, wear, and moisture, ensuring long-term reliability in critical applications.
