Product Name: Torque Wrench 1 Drive Product material: Chrome-vanadium steel Product quantity: 1*torque wrench, 1*storage box, 2* screws, 1*1/4 bits socket-H5 Product Packaging Size: 41.34*8.47*3.43 Inch Net weight: 22.05 Lbs This torque wrench meets ISO 6789 standards, endures 10,000+ fatigue tests, and maintains 3% accuracy-ideal for tightening heavy-duty bolts. A small tip: Use it within the 20%-85% torque range and reset to zero after use; this prevents the internal spring from constant tension, sustaining precision longer and extending service life. This 1 Inch torque wrench has a distinct-visibility dual scale and seamless bidirectional adjustment for tightening/loosening. Its laser-engraved markings help resist wear, keeping clarity during long-term use in large construction, mining, oil/gas, rail, and marine engineering scenarios. The legible scale supports efficient torque setting in these heavy-duty fields, helping reduce visual strain during on-site or shop tasks. Designed for precise torque application, this 1 torque wrench delivers an immediate loud, clear clickwhen reaching preset torque-stopping operation timely to avoid excessive tightening that might damage fasteners. It has a split-body structure (front holds torque preset mechanism, plus an extension rod 15% longer than one-piece wrenches) to reduce force needed for preset torque. The clickcuts through job site noise, and its 24-tooth reversible ratchet stays intact after 10,000+ fatigue tests-suiting rail/transit, oil/gas, construction, and mining tasks, working smoothly with no mid-task second-guessing. This 1 inch torque wrench is made of chrome vanadium steel (CR-V) for lasting strength, plus a wear-resistant chrome plating that stands up to oil, debris, and tough conditions. Its lightweight aluminum alloy handle eases maneuvering when tightening large mining truck wheel nuts, helping avoid extra hand fatigue during long sessions.
