​​Professional Grade Double Head Wrench Set With Extended Handle For Extra Reach

​​Professional Grade Double-head Wrench Set With Extended Handle For Extra Reach

The ​​Lengthened Double-head Wrench​​ is an essential tool for professionals who require extended reach and high torque capability in mechanical and industrial applications. Designed with dual ends (typically different sizes) and an elongated handle, this wrench provides superior leverage and accessibility, making it ideal for working in confined spaces or on large machinery where standard wrenches fall short.

Crafted from ​​high-grade chrome molybdenum steel (Cr-Mo)​​, this wrench offers exceptional strength and durability, capable of withstanding extreme torque without bending or breaking. The heat-treated alloy ensures maximum hardness (HRC 48-52) while maintaining toughness, and the black oxide or chrome-plated finish enhances corrosion resistance for long-term use in harsh environments.

​​Key Features:​​

• ​​Extended handle design​​ for increased leverage and reach
• ​​Dual-head configuration​​ with two different size openings (e.g., 10mm x 12mm)
• ​​Precision-machined jaws​​ for secure grip on fasteners
• ​​Anti-slip ergonomic grip​​ reduces hand fatigue during prolonged use
• ​​Reinforced neck and beam​​ for high torque applications (up to 300Nm)
• ​​Laser-etched size markings​​ for quick identification
• ​​Black oxide/chrome finish​​ for rust and corrosion resistance

​​Technical Specifications:​​

• ​​Material:​​ Chrome Molybdenum Steel (Cr-Mo)
• ​​Hardness:​​ HRC 48-52
• ​​Finish Options:​​ Black Oxide / Chrome Plated
• ​​Length:​​ 250mm – 600mm (varies by model)
• ​​Head Sizes:​​ Various combinations (e.g., 8mm-10mm, 12mm-14mm, etc.)
• ​​Weight:​​ 0.5kg – 2.0kg (depending on size)

​​Safety and Performance Advantages:​​
✔ ​​Reduces effort by 30%​​ compared to standard-length wrenches
✔ ​​Prevents fastener rounding​​ with precise jaw engagement
✔ ​​Ideal for deep or recessed bolts​​ where standard tools can’t reach
✔ ​​Resistant to oil, grease, and chemicals​​ for industrial durability

​​Professional Applications:​​

1. ​​Automotive repair​​ – engine, transmission, and suspension work
2. ​​Heavy machinery maintenance​​ – construction and agricultural equipment
3. ​​Industrial assembly lines​​ – large-scale bolt tightening
4. ​​HVAC and plumbing systems​​ – hard-to-reach pipe fittings
5. ​​Manufacturing plants​​ – equipment installation and maintenance

​​Available Configurations:​​

• ​​Standard lengthened double-head wrench​​ (fixed sizes)
• ​​Adjustable head wrench​​ (for multiple fastener sizes)
• ​​Flex-head extended wrench​​ (for angled access)
• ​​Extra-long industrial wrench​​ (for deep-reach applications)
