Technical Specifications

Material & Manufacture

Bars  are made from a heat treated alloy and threads are rolled to provide greater fatigue resistance. All material is independently tested for mechanical properties.

Stainless steel high strength threaded bar is also available - please contact our technical department for more information.

  • European made
  • ISO 9001, 3.1 certification
  • Third party tensile & NDT tests available on request
