This practical set includes the most commonly used metric sizes from 1.5 mm to 10 mm, making it a reliable choice for professional technicians, mechanics, installers, and serious DIY users.

Manufactured from high-quality CrV 6150 chrome-vanadium steel, these hex keys offer excellent strength, elasticity, and resistance to wear under regular working loads. With a hardness of 52–56 HRC, they are built to deliver dependable performance and long service life in demanding workshop and maintenance environments.
Each key features a ball end tip, allowing operation at an angle of up to 25°.
