  • PEEK is a thermoplastic super-engineering plastic with excellent physical and chemical properties.
  • These screws have excellent chemical resistance. They are mostly unaffected by chemicals excluding concentrate sulfuric acid, concentrate nitric acid, and concentrate hydrofluoric acid.
  • These screws have excellent heat resistance, water resistance, and high heat resistance strength.
  • These screws have excellent abrasion, shock, and fatigue resistance.
  • They have high incombustibility that meets V-0 of UL 94.
  • The properties and precautions of plastic screws⇒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 or less fit with female thread.
