Special screws with high chemical resistance

The chemical challenge in the industrial environment

In many industrial processes, aggressive chemical agents such as hydrochloric acid (HCl), sulphuric acid (H₂SO₄), hypochlorite, hydrofluoric acid (HF) or even substances such as hydrogen peroxide (H₂O₂) have a high degradation potential on traditional metal components.

These substances, present in industries such as chemistry, microelectronics, water treatment, pharmaceuticals, food or wafer etching and  cleaning processes, attack metal surfaces, causing:

• Accelerated corrosion
• Loss of torque
• Chemical or mechanical leaks
• Contamination of critical processes

Standard screws, even in stainless steel, often does not provide the strength needed for these environments.
