The HRT process (High-Resistance Thread) was the result of a further development of the RIVKLE® technology.
Progressive materials and processes allow to produce a reinforced, higher-strength thread which considerably improves the mechanical properties of the RIVKLE® blind rivet nut.
Thread as per ISO 6H (ISO 68-1) corresponding with screw property class 10 or 12 (compatible screw property classes 10.9 and 12.9).
Advantages: • Higher preload forces in the joint due to higher torques • Use of smaller thread sizes possible • Reduced weight • Corrosion resistance, particularly with aluminium • Improved recyclability (aluminium RIVKLE® HRT and aluminium component)
