Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Versatile Fastener Adjustment: Designed for precise tightening and loosening of nuts and bolts with a double open-end configuration, supporting auto repair, mechanical maintenance, and general assembly tasks.
  • Durability & Corrosion Resistance: Chrome vanadium steel construction ensures long-lasting performance in harsh environments, resisting wear, rust, and corrosion.

Key features

  • 1. Material Technology

    • With chrome vanadium steel construction, you can achieve long-lasting durability and corrosion resistance in harsh environments. This alloy ensures minimal wear over time, outperforming standard steel tools by up to 30% in strength*.

  • 2. Interactive Design

    • The double open-end design allows you to quickly switch between two sizes per wrench and access bolts in tight spaces. This reduces the need to frequently change tools, improving efficiency by ~20% compared to single-ended wrenches*.

  • 3. Performance Parameters

    • Equipped with a full metric size range (e.g., 18–30mm), you can tackle a wide variety of bolts and nuts, ensuring compatibility with global automotive and mechanical standards. The precise sizing minimizes slippage and damage to fasteners.

  • 4. Scenario Solutions

    • Designed for automotive and professional mechanical tasks, these wrenches balance versatility for home repairs and reliability for commercial use. The ergonomic handles and corrosion-resistant coating make them ideal for frequent, heavy-duty applications.

  • 5. Certification Standards

    • Compliance with EN IEC 55014 and EC 1907/2006 (REACH) ensures safety and eco-friendly material use, meeting rigorous international quality and environmental regulations.
