Characteristics

  • Inch screw type.
  • PEEK is a thermoplastic super engineering plastic superior in physical and chemical properties.
  • Excellent chemical resistance. It remains almost unaffected by chemicals other than concentrated sulfuric acid, concentrated nitric acid, and concentrated hydrofluoric acid.
  • With excellent heat resistance and water resistance, it retains strength at high temperatures.
  • It features outstanding resistance to wear, shock, and fatigue.
  • It also has high flame retardance which clears the UL 94 V-0 standard.
  • Plastic screw properties and precautions for use ⇒Plastic Screws

Precautions for Use

Because a cumulative pitch difference is created when PEEK screws are manufactured, use these screws with nuts. If a nut is not used, use a 20 mm (approx. 0.79") or less fit with female thread.
