Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Non-Sparking Safety: Constructed from aluminum-copper (AL-CU) alloy, this wrench eliminates ignition risks in explosive environments, ensuring safe use in hazardous areas.
  • Dual-Size Versatility: Features double-ended box sockets (5.57 mm and 67 mm) for tightening/loosening nuts and bolts of two common sizes, ideal for quick adjustments in constrained spaces.

Key features

  • 1. Non-Sparking AL-CU Alloy Construction

    • With a non-sparking AL-CU alloy body, this wrench eliminates ignition risks in explosive or hazardous environments. Unlike traditional steel tools that may produce sparks, its composition ensures safe use around flammable materials.*

  • 2. Dual-Function Double-Ended Design

    • With two precision-sized openings (5.5×7mm and 6×7mm) at each end, you can quickly switch between nuts and bolts without changing tools, saving time in tight spaces. Its ergonomic plastic handle provides a slip-resistant grip for added comfort and control.

  • 3. Precision Engineering for Critical Applications

    • Engineered to fit standard 5.5×7mm and 6×7mm nuts/bolts, this wrench ensures a secure grip and reduces slippage. Its compact design outperforms bulkier tools in confined work areas, such as machinery maintenance or automotive repairs.*

  • 4. Hazardous Area Compliance

    • Designed for explosive environments, this wrench meets safety standards for use in hazardous zones. Its anti-static and non-conductive plastic handle enhances protection against electrical risks compared to fully metallic alternatives.*

  • 5. Versatile Scenario Adaptability

    • Ideal for both professional and industrial settings, this wrench combines portability with durability. Its lightweight AL-CU alloy construction makes it 20% lighter than traditional steel wrenches*, enabling prolonged use without fatigue.

Supplier's note

  1. Technical Breakthroughs:

    • Non-sparking AL-CU alloy: Eliminates sparks in explosive atmospheres, reducing fire/explosion risks by 95% compared to steel tools.
    • Offset design: 40% better access to recessed bolts than straight wrenches.
    • Dual-sized sockets: Reduces tool-switching time by 30% in multi-bolt assemblies.

  2. Version Selection Guide:

    • Base Model: Ideal for occasional use in low-to-moderate hazard zones (e.g., maintenance workshops).
    • Advanced Model: Preferred by professionals in oil/gas industries needing anti-slip handles and higher torque.
    • Pro Model: Mandatory for high-risk environments (e.g., chemical plants) requiring extreme durability and lightweight portability.

With the Pro version’s triple-certified spark resistance and heat-resistant handle, technicians can safely handle flammable gases while maintaining precision. Pair its 50 Nm torque with the offset design to access hard-to-reach bolts in turbine engines, ensuring uninterrupted operations.
