Feature●Accurate torque value - ±3% error accuracy, each torque wrench undergoes 10,000 machine up and down pressure tests, and each torque wrench is calibrated by a professional machine, with higher accuracy and longer service life and meets the requirements of ISO06789.GB/T15729.ASME and ASME B107.14M. Each product has a separate calibration certificate and numbering.●High-quality materials - ratchet made of a high-hardness 40CRV alloy (chrome vanadium steel), non-slip, rust-proof, high quality, laser scale is clearer, higher accuracy, easy to read. The fittings are made of S2 tool steel with good impact resistance, hardness and toughness.●Versatile set: Torque wrench 13 set includes: torque wrench, hex bits H10, H8, H6, H5, H4, H3, H2.5, H2, Torx T30, T25, T10, 1/4 inch x 100 mm extension rod.●Easy to use - 72 reversible ratchet, clockwise counterclockwise two-way adjustment. Torque wrench is equipped with a quick release button that can easily install and remove the socket. Adjustment of the torque value: press to lock, set torque value, release, automatic locking of the torque value. Adjustable range 1-25Nm, smallest step width 0.2Nm.●Safe and reliable - When the preset torque value is reached, the torque wrench makes a click sound. At the same time, an obvious vibration of the hand is accompanied to induce the completion of the work. Remind you to stop using force, to prevent expensive damage caused by too much tightening.●Widely used - ratchet box wider application on bicycle/mountain bikes/motorcycle maintenance for use on stems, seat clamps, lever clamps, rotors, chain sets and cranks etc. Also suitable for repair/installation of household appliances, electrical engineering, product assembly, mechanical repair, daily life, etc.Description
