Medium To High Torque Wrench

1、 Core parameter table
Project Details
Drive specification 1/2 “square head (compatible with all 1/2” sockets in the series)
Torque range 40-220N · m (synchronous conversion: 29.5-155lbf · ft)
Adjust resolution to 1N · m (clear scale, precise adjustment)
Accuracy level ± 3% (industrial grade high precision, meeting strict standards)
Net weight of wrench 1.222kg (lightweight long rod, balanced handling)
Total weight including packaging 1.7kg
Packaging size 58 × 10.3 × 6 cm (hard box, protective storage)
2、 Core Performance: Precision, Efficiency, and Durability
1. High precision torque control
± 3% error+1N · m resolution: laser etched scale ring with damping knob, torque setting and output height consistent, eliminating the risk of over twisting (such as engine bolt breakage) or under twisting (such as chassis abnormal noise), suitable for precision assembly needs of automobiles and industries.
Wide range coverage: 40N · m (light equipment) to 220N · m (heavy fastening), easily handling scenarios such as tires (80-120N · m), suspensions (120-180N · m), motor bases (180-220N · m), etc.
2. Efficiency breakthrough of 1/2 “ratchet head
Bidirectional fast reversing: the lever switches between forward and reverse rotation, and there is no need to flip the wrench when disassembling bolts, increasing efficiency by more than 50%; The bite teeth are fine and can maintain stable transmission even in humid/oily environments, avoiding “idling and slipping”.
Adaptability of large drive: 1/2 “square head compatible with a large number of sleeves, covering M10-M24 grade bolts, one-stop solution for multi specification fastening needs.
3. Mechanical advantages of long pole design
Effortless lever: 58cm long rod (reflected in packaging size) amplifies torque, making it easier to grip with the same torque (compared to short handled wrenches, saving more than 30% effort), reducing fatigue from long-term work.
Alloy rod body: forged from chrome vanadium steel, with strong torsional resistance, wear resistance, and corrosion resistance. The long-term use accuracy attenuation rate is lower than the industry average, ensuring stable performance.
3、 Design and scene adaptation
1. Detail design
Anti slip handle: wrapped in rubber and with ergonomic texture, it can be firmly held in sweaty/oily environments, avoiding operational errors.
Locking knob: After adjustment, it locks to prevent accidental torque changes during operation, ensuring safety and accuracy.
2. Typical application scenarios
✅ Automotive deep maintenance: tire bolts (80-120N · m), engine mounts (150-200N · m), chassis suspension (120-180N · m);
✅ Industrial assembly: high torque bolt fastening for heavy-duty motors, gearboxes, and construction machinery;
✅ Equipment maintenance: Standardized torque maintenance of electromechanical equipment such as generators and compressors.
