Through hardened screws

HPT screw series

HPT series screws are manufactured from specially developed tool steels sourced from leading European producers. Thanks to precise heat treatment, they meet the most demanding requirements for processing modern polymers. These materials, featuring key alloying elements such as chromium, molybdenum, tungsten, and vanadium, ensure excellent resistance under extreme conditions. The series is an ideal choice for applications involving high pressure, high temperatures, and abrasive wear, even at high peripheral screw speeds.
