Precision for European fasteners

The JU JIAN TEC XZN Triple Square Bit Socket Set is a focused, 10‑piece collection designed for European automotive fasteners. Crafted to feel reliable in routine service, this kit combines sturdy materials with finish details that help you work smoothly, even when you encounter snug or stubborn heads under the hood.

Premium materials and finish

Bits and sockets are drop‑forged from premium chrome vanadium steel, delivering balanced hardness across profiles. Sockets receive a chrome plated mirror finish for a polished surface that cleans easily after use, while bits benefit from a zinc phosphate treatment to enhance rust resistance without compromising accuracy.

• Drop‑forged construction for consistent strength
• Chrome plating on sockets for a smooth finish and easier cleanup
• Zinc phosphate on bits for added corrosion protection
