Product Name: 3/4 Torque Wrench 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: 21.16 Lbs For truck or equipment bolt tightening, redoing work is avoidable with this 3/4 drive torque wrench-it endures 10,000+ fatigue tests, keeps 3% accuracy, and includes a calibration certificate, no second-guessing bolt tightness to stay on track. Tip: Use it within the 20%-85% torque range and reset to zero after use to maintain precision longer and ensure reliable durability. This 3/4 torque wrench has a chrome vanadium steel (CR-V) body-built to last, oil and grime resistant-and an aluminum alloy handle for a comfortable grip. Even after hours of use, no palm ache, and hold stays steady; it works smoothly for semi-truck tire nut tightening or passenger bus part adjustment. When kneeling to change a truck tire or fix heavy machinery (greasy hands, in a hurry), a tricky scale is unwanted. This 3/4 inch torque wrench has laser-etched dual scales (100-800 Ft-Lb/135.6-1084.8 N.m) that resist oil and grime-pick Ft-Lb or N.m instantly with no conversions, and marks stay clear in the field, no squinting. This 3/4 drive torque wrench is easy to use: pull the lock knob down, set torque, let go-it locks in, no fuss with tricky settings. Its split-body structure (front holds torque preset mechanism, plus an extension rod 15% longer than one-piece wrenches) cuts muscle needed for preset torque. When preset torque is hit, youll feel vibration or hear a loud click-no straining over truck engines or power tools. The 24-tooth reversible ratchet stays intact after 10,000+ fatigue tests, working smoothly and reliably for heavy truck/bus repairs, industrial piping, construction, and farm/forestry machinery, no mid-job second-guessing.
