Overview of Basic Parameters Drive specification: 1/2 "square head (compatible with mainstream 1/2 inch sockets) Torque range: 20-120N · m (corresponding to imperial units: 14.8-88.6ft.lb) Net weight (wrench): approximately 1.4kg (including total packaging weight of 1.6kg) Packaging size: 49 × 10 × 6 cm (compact design, more convenient for storage/carrying) Precise torque output Adopting a high-precision adjustment system, the scale ring is laser etched, the damping of the adjustment knob is uniform, and the torque setting error is controlled within the industrial standard to ensure that the bolts/nuts are tightened according to the specified torque, avoiding over tightening, fracture or over loosening failure. Efficient operation of bidirectional ratchet The 1/2 "ratchet head supports fast forward and reverse switching (operated by the head lever), eliminating the need to flip the handle when disassembling bolts, greatly improving work efficiency;the ratchet teeth are tightly engaged, ensuring no idle transmission and more stable torque transmission. Design and Material Analysis 1.Structure and Material Rod body: Forged from high-strength alloy steel, it has strong torsional resistance, wear resistance, and corrosion resistance, and is not easily deformed after long-term use. Handle: Non slip rubber wrap, ergonomic design, comfortable grip, reduces operational fatigue. Adjustment area: Metal scale ring+locking knob, locked to prevent misoperation after adjustment, more reliable torque output. 2.Storage design Equipped with a hard plastic protective box, the internal groove precisely adapts to the wrench, isolates dust and bumps, and facilitates tool management and outdoor carrying. Applicable scenarios ✅ Car maintenance: tire bolts (recommended 80-120N · m), brake system, suspension component fastening, etc. ✅ Industrial assembly: Standard torque installation for medium-sized mechanical equipment (such as pump bodies, gearboxes) and hardware workpieces. ✅ Home engineering: assembly and maintenance of large furniture (solid wood beds, cabinets) and electric tools (bench drills, grinders).
