• High-strength Protanium® steel is produced according to a formula that is the result of many years of research and continuous improvement.
• A specially selected heat treatment process is key to achieving the unique properties of Protanium® steel.

• The application process of this layer begins with a thorough cleaning of the wrench's surface from any dirt or rust.
• The resulting finish makes the surface highly resistant to moisture or contamination penetration.
