Our Production
Advanced cold-forming and thread-rolling lines produce screws to our own design or to your exact specification — diameters up to 7/16″ and lengths to 24″.
Heat Treatment
Continuous-furnace case hardening delivers case hardness of HV 420–500 over a tough HV 300–390 core — the basis of our torsional and bending performance.
Quality Assurance
Torque-strength and bending-curve testing plus hydrogen-embrittlement control keep every lot within CE, ETA and ICC-ES requirements.
