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
